The HealthyAir® Oral Aerosol Vacuum & Air Purification System is the leader in protecting dental professionals from harmful aerosols. As contaminated air passes through the HealthyAir® Source Capture, the Pre-Filter, eHEPA® Filter, and Enhanced Carbon Catalytic Filter work in conjunction to capture ultra fine air borne particles and microorganisms, including virus, bacteria, mold, gasses, dust, smoke, allergens, odors, and VOCs, as well as mercury particulate and vapors. The unit ships with a 5′-6″ hose.

These units can be converted to an outside ventilation unit with the provided hardware.

The HealthyAir® Oral Aerosol Vacuum & Air Purification System also has an enhanced carbon catalytic filter which enables the system to be used for the Safe Mercury Amalgam Removal Technique (SMART) to capture harmful mercury vapors and mercury particulate that are released during the removal of amalgam fillings. More information can be found in our comprehensive FAQ below.

Again, all HealthyAir oral aerosol vacuum units ship as recycled air units, but can be converted into outside vented units at your convenience.

FREQUENTLY ASKED QUESTIONS

If you do not see your question listed below, please email us at HealthyAir@dentalsafetysolutions.com and we will respond to your inquiry and then post the answer to the FAQ.

All new orders starting from 6/16/2020 will ship with a 5′-6″ hose (previous units shipped with a 6″ hose)

Regarding the concern about the flexible hose, let me first explain our rational to use this type of hose for the dental aerosol extraction, as there are other extraction arms such as the articulating metal arms that you may see provided with some other units. Based on many feedbacks we have received from the dental community, the concern is accumulation of germs in the articulating metal pipe and connecting joints, which are very difficult to clean and sanitize. Therefore, we have gone with the flexible hose where we further process it to make it more rigid and self-supporting. Accumulation of germ is much reduced in this hose and further sanitization of it is practical. Some offices maintain a spare hose, where they interchange while they sanitize the other one, with the use of a brush with a long handle and sanitizing liquid applied over a sink. We could provide you with information on the proper brush, or pricing for additional hose/hood.

The slumping of the 6″ hose occurs when the hose length goes beyond 5ft, and depends on the way the hose shaped. Attached are two set up A and B. Set up A is more stable than set up B. The hose provided with your unit ( including the hood) is about 6Ft long ( 5’ -6” hose + 6” hood). If you can place the unit closer, then you could shorten the length by removing a small section. To remove a small section, you need to unscrew the hose clamp and remove the hose assembly from the inlet tube. Then you could pull on the interlocking strand and unwrap it a few rounds. You could then cut it with a scissor.

As soon as your order is processed in our system, UPS sends a notification via email informing you of the tracking numbers associated with your shipment. Your order will ship approximately 5-7 business days after. Due to high demand lead time for shipping is longer than usual, but please know we are working very hard to get orders out in a timely manner, so your patience is appreciated.

With patented eHEPA® technology, The HealthyAir® Oral Aerosol Vacuum System effectively cleans air in a highly efficient and innovative 3-stage process that captures and removes harmful molecular air pollutants and ultra fine airborne particles including volatile organic compounds (VOCs), bacteria, virus, mold, fungi, odors as well as mercury aerosol and vapor.

The HealthyAir® Oral Aerosol Vacuum system ships as a recycled air unit, but it can be configured to discharge treated air out of the facility via an exhaust duct connection to the 4” dia. outlet port of the unit. This is important as this configuration provides negative pressure in the room to minimize leakage of contaminated air to the other rooms in the facility.

The HealthyAir Oral Aerosol Vacuum unit comes with the required parts to configure it as an outside venting unit (if you choose at some point in the future). The manual shows this on page 12 (below). The blank-off plate for the bottom and the flange for connection to the exhaust duct are in the same package as the main body of the unit.

We do not supply the exhaust duct to the outside. There are various options for that and any HVAC contractor should be able to install that and connect it to the unit. Depending on the dimensions and if multiple units are fed into a common exhaust duct, they may need to size up the exhaust ducting from a 4” duct to something greater in diameter.

Negative pressure in the room (so that air flows under the door gap into the room) and leakage of contaminated air is avoided into the other rooms. HealthyAir® Source Capture System can be set up to provide multiple air changes per hour.

The air change/hr (ACH) is a simple calculation as follows:

1: calculate the volume of air in the room, for 10’x 10’ with 8’ celling, the volume will be 800cubic ft. Then the single inlet unit at the mid speed moves 90 cfm, so in one hour 90 x60 min/hr = 5,400 cubic of air has been treated by the unit. You then divide 5,400 / 800 and get 6.75, meaning that the air in the room goes 6.75 times through the unit per hour. ACH of 6 is generally recommended for the existing negative pressure rooms. At high speed, the unit delivers 130 cfm, so the ACH would be 9.75.

Larger rooms would require more CFM. One approach could be to use HealthyAir® Source Capture dual inlet unit with 122 CFM rating at mid speed. This will provide ACH of 6.35 for a 12’ x 12’with 8’ ceiling. Possible use of the dual inlet unit would be to use one hose for source capture and the other for general air extraction for another side of the chair or another location in the room.

Off course this is just an approximate number, as the air in the corner of the room may have a longer time to go through the unit, than the air close to the air purifier. But that is what is used to specify the ACH. Think of your swimming pool and the filter system. If you pass the dirty water in one section through the filter most of the time, instead of the water in the other side of the pool which may be cleaner, then the resulting pool will be much cleaner. That is the concept of source capture.

REGARDING CFM (see attached graphic)
Every fan has an airflow/pressure curve, as shown in the attached graphic.  The free delivery is when the fan is running by itself outside of any enclosure, where there is no resistance to air flow.  A lot of air purifiers specify the free delivery as the air flow rate, which is very misleading and means nothing about the actual unit. Dentairvac statement of 770 cfm and 12 air changes is not correct.  Note that in the same spec, they then say the fan rating is noted as 770 cfm.  There is a big difference when you put a fan with this rating into a box and connect a hose to it.  The resulting CFM is much less.
When you install the fan in an enclosure with some filters, that create resistance to flow of air, or pressure drop, inch of water.  There is a relationship between the airflow through that system and the pressure drop.
That is the yellow line in above picture.  When that line intersect the fan curve, that establishes the actual flow rate of the unit,  that is the 130 CFM of the Healthy Air unit.  That CFM is constant through out the unit, what ever it is at the inlet of the hose, it is the same through the unit and that is what discharges, this is conservation of mass.  Whatever goes in, must comes out.
Turning the electrostatic on and off with the eHEPA filter would not change the air flow.  The only thing that change the air flow is the fan speed.  Also, as particulate builds up on the filter, it slowly begins to increase the flow resistance and over time the collected particulate will plug the filter and prevent any flow through the unit, same as your vacuum cleaner with full bag.  This is one of the advantages of our technology.  Our technology does not use as dense a filter as standard HEPA in high end units like IQair.  Therefore,  our filter can tolerate much more particle build up before it slows down the flow.  This is what is referred to as dust holding capacity of filter, which we state that ours has four times more dust holding capacity as regular HEPA.  It means that it needs to be replaced less frequently than other HEPA filters.

The approximate weight and base dimensions of the unit is: 45 lbs. – 12” x 14” w x 21” h. The extraction arm hose length is 6 feet long. This portable floor unit is designed to be positioned in close proximity to the workstation, however in some cases remote location of units is required.

Yes, by easily adjusting the flexible hose, the hoods of the extraction arms can be strategically positioned to capture impure air.

We ship out a single 6 foot hose with each unit. While we can make a custom hose length, please be aware that it will not be as self-supporting though; it will be semi-rigid and may require the user to prop-it up or anchor it somehow. Also, the length of the hose will affect the CFM at the inlet of the hose.

  • Increasing hose length, increases the pressure loss which decreases the CFM
  • Increasing hose diameter, decreases the pressure loss and increases the CFM

The healthy Air units offer a simple remote-control operation and is equipped with a three-speed fan that enables control of air flow and sound level.

Low Speed: 54 dBA
Medium: 56 dBA
High: 64 dBA

One cannot have powerful oral suction without noise from a fan as the more cfm and pressure you treat, there will be more noise. To help with this, we have now added an acoustic mat that comes with the unit and should be place on the floor and then the unit is placed over it. It will reduce the noise that bounces from the finish floor, especially if the floor is tile and not carpet. Some have actually put the unit inside a cabinet with the hose running out.

We are working towards offering a disposable plastic cover that would go over the outside of the front and inlet of the hose. But at this time we do not have a specific product for sale. Until then, one can utilize the plastic head rest cover from their dental chair and cut a hole in it to place over the front of the hose inlet as seen in the picture to the left.

Possible issues are unraveling of the hose, especially at the connection point to the unit.  It is a spiral construction, and possible to put it back together.  Although I doubt a dentist would want to do that.  We have them in stock.  For the past five years, we’ve had very few cases, out of few thousand units. The hose connection into the inlet is a clamp on style.  You will need to clamp it down, preferably with a nut driver screw, instead of a screw driver to make sure the hose is tightly fitted to the inlet tube.  Otherwise, the hose will keep coming out.

Yes, each HealthyAir unit will come with an Integrate Filter Set (IMF) that will last roughly 400 hours.

When the unit has been in operation for 400-hours, the Filter Change indicator light, on the Control Panel, will begin to flash indicating that the filters must be replaced as follows: Note: Depending on usage and contaminates in the environment, the filter may need to be replaced before the 400-hour default cycle expires as the need for filter replacement naturally varies depending on the frequency and nature of use.

The Integrated Filter Module replacement filter is compatible with this unit.

The HealthyAir® Source Capture System is the ideal system for use in dental offices for both virus and mercury removal, there are a multitude of commercial settings where it can be used such as beauty salons, prosthetic labs, nursing homes, nail salons and more.

Just to be clear. We are not selling medical air purifiers. The HealthyAir units are source capture for general use that has technology for filtering ultra-fine particles through the use of electrostatics that also has some inactivation benefits.  But we are not offering these as medical grade devices.

The Healthy Air unit has a unique eHEPA® (electrostatic) filtration system uses a multi-stage process that captures and removes harmful molecular air pollutants and microscopic airborne particles, including volatile organic compounds (VOCs), bacteria, virus, mold, fungi, odors as well as mercury and other hazardous gases and particulate. please see the documents below for more information.

If you’d like to know more about electrostatic filters, please read the study “Airborne Virus Capture and Inactivation by an Electrostatic Particle Collector”
Environ. Sci. Technol. 2009, 43, 5940-5946. The study examines the efficacy of electrostatic filters (such as our eHEPA). This type of technology is also rated very high by the CDC (see attached chart from CDC).

UVC ultraviolet light has long been established to kill virus and bacteria, and its also in widespread use in public settings,  but UVC light sources use a high electric power ( watts), and is a slow process that requires costly replacement of the bulb.  The electrostatic utilized with eHEPA technology we use is in competition with that UVC and we think has an advantage over UVC.  Since UVC is a light source,  it only cleans the germs on the face of the filter and it takes about 30 min to actually deactivate the germs (virus and bacteria).  Our technology uses electrostatics to penetrate the entire depth of the filter media, not just the face, and also, it kills germs in flight, while they are passing through the active ionizing region.  It uses 1/10th  of electric power as compared with UVC light bulbs and does not need replacement. One challenge is this technology is not widely known.

The CDC has written a great article

Interim Infection Prevention and Control Recommendations for Patients with Suspected or Confirmed Coronavirus Disease 2019 (COVID-19) in Healthcare Settings.

once on the CDC page, go down and read #4

Take Precautions When Performing Aerosol-Generating Procedures (AGPs)

  • Some procedures performed on patient with known or suspected COVID-19 could generate infectious aerosols. In particular, procedures that are likely to induce coughing (e.g., sputum induction, open suctioning of airways) should be performed cautiously and avoided if possible.
  • If performed, the following should occur:
    • HCP in the room should wear an N95 or higher-level respirator, eye protection, gloves, and a gown.
    • The number of HCP present during the procedure should be limited to only those essential for patient care and procedure support. Visitors should not be present for the procedure.
    • AGPs should ideally take place in an AIIR.
    • Clean and disinfect procedure room surfaces promptly as described in the section on environmental infection control.

Formerly, negative pressure isolation room, an AIIR is a single-occupancy patient-care room used to isolate persons with a suspected or confirmed airborne infectious disease. Environmental factors are controlled in AIIRs to minimize the transmission of infectious agents that are usually transmitted from person to person by droplet nuclei associated with coughing or aerosolization of contaminated fluids.

AIIRs should provide

  • negative pressure in the room (so that air flows under the door gap into the room);
  • and an air flow rate of 6-12 ACH (6 ACH for existing structures, 12 ACH for new construction or renovation);
  • and direct exhaust of air from the room to the outside of the building or recirculation of air through a HEPA filter before retruning to circulation (MMWR 2003; 52 [RR-10]; MMWR 1994; 43 [RR-13]).

Here are the CDC Engineered specifications for positive- and negative pressure rooms, and a handy pdf on how to create Airborne Infection Isolation Rooms.

Fuses

Sometimes fuses can go bad or burn out. We sell spare fuses, or we can let you know the brand / model and have you replace it.  It is in the socket where you plug the cord in for the portable units.

The safety switch: 

Every time, the filter access cover is removed for filter change, this switch will shut of the power.  It is important to place the access cover correctly and tightly so that the switch makes contact.  Sometimes, people replace the filter and don’t replace the access cover tight.  Then the unit will not power up.

Switch failure has occured, meaning the unit did not power up.  Switch needs to be replaced, we have these in stock, not a hard job to change.  But we recommend a HVAC type electrician/technician to change them.

PCB Boards

There are two PCB boards.  One is the main board, the other is the display board.  Display board is simple to replace and is low voltage.

We have had issues with these as we once received a shipment with all faulty boards.  It is coming from China, and even with the QC stamp both on the board and the unit, we get surprised once in a while.

Again, we have them in stock.  It is best to encourage the customer to hire a local electrician/technician to replace these, with us sending them the board and instructions.

The main board is little harder to replace.  Again, an electrician/technician that services the HVAC unit could easily replace these with our parts and instructions.

From time to time, people will return units for warrantee repair ( during the first year) or regular repair.  We charge $ 150 flat for the repair, plus the UPS charge.

Yes, all HA units comes with remote control. They can operate the unit via remote or via the push buttons on the unit. The remote is RF signal.

The eHEPA filters are a hybrid filters that use a lower MREV rated filter, add electrostatic field to it to result in a filter with higher equivalent MERV ratings.  Standard units have an equivalent MERV rating of 16/17, while units can be made with even higher equivalent MERV rating to E12/H13.
We will keep this page updated as we introduce other filter modules.

The Healthy Air unit comes with a 1-Year Limited Warranty (“Limited Warranty”) to the original retail purchaser who submits the Warranty Registration Card that comes with the system, within 10 days of purchase.

We have replaced only one fan/motor in the past five years.  We have them in our inventory.  Not a hard task to replace these for the portable units.  We have not had to change any so far.

The science is clear. The process of removing amalgam fillings generates vast amounts of both mercury vapor and mercury contaminated particulate matter that become aerolsized in the breathing zone of the dental professionals. The ultra-fine mercury particles are filtered out in the eHEPA filter, while the gaseous mercury is captured by the activated carbon filter, which is the final filter within the Integrated Filter Module (IFM).

When mercury is captured by activated carbon, both physisorptive as well as chemisorptive mechanisms come into play.  Untreated activated carbon, which is used in the Healthy Air IFM modules, captures gaseous mercury by physisorption, like a porous sponge collection.

Treated activated carbon, which will be available by this fall captures mercury by both mechanisms and provides an even higher filter life before replacement is needed, which is estimated to be as much as three to four times higher.

Please read this article: Can HEPA Air Purifiers Capture the Coronavirus? where it states…
The virus that causes COVID-19 is approximately 0.125 micron (125 nanometers) in diameter. That falls squarely within the particle-size range that HEPA filters capture with extraordinary efficiency: 0.01 micron (10 nanometers) and above. Many media outlets have incorrectly stated that HEPA filters don’t filter below 0.3 micron, and therefore could not capture airborne coronavirus. That is incorrect. (This NASA study of HEPA filtration is quite technical, but the graph on page 7 and the preceding paragraph do a good job of explaining why HEPA filters are actually most efficient—almost 100 percent at 0.01 micron—at capturing ultrafine particles below the 0.3 micron HEPA test standard.)

FILTRATION

The Healthy Air has a unique eHEPA® filtration system uses a multi-stage process that captures and removes harmful molecular air pollutants and microscopic airborne particles, including volatile organic compounds (VOCs), bacteria, virus, mold, fungi, odors as well as mercury and other hazardous gases and particulate. An Integrated Filter Set comes with the system.
The DentAirVac only comes with a HEPA filter, which will not filter as many hazards as efficiently as the eHEPA. Please see the documents below for more information about the difference between the filter technologies. DentAirVac doesn’t allow us to sell filters or accessories so we don’t have a cost comparison.

THE MACHINE

HealthyAir
Every Healthy Air unit comes with the option to vent it to the outside and an electronic front panel for controlling all settings, such as fan speed (low, medium, high). It also ships with a mat to place under the system that will decrease the noise level of the machine. Additionally, the HealthyAir unit keeps track of filter usage and will alert you when it is time to change it out (roughly 400 hours). The DentAirVac is not capable of any of this.
DentAirVac
no eHEPA filter
no vent to outside
no electronic settings
no mat

4 decibels louder at high mode

The HealthyAir units are meant solely for suctioning aerosols from the air that have been generated during dental procedures. This device is not and should not be used as a traditional vacuum, because it is not one.

Below is a paper that is sent inside every package to remove the wrapping of the filter. Some customer may think the unit does not have much suction, that could be due to them not removing the wrapping of the filter.

We have partnered with www.myus.com to provide international shipping. We can ship only to Canada directly for 2 or more units.

At this time, due to the sheer volume of calls we have been receiving all correspondence is being done through email.  We will respond to your inquiry the day we receive your email. Additionally, we have suspended taking orders by phone and all orders are being placed through our website.

We thank you in advance for your understanding and patience.

The Healthy Air units will come with a small low voltage electrical connection coming out of the top of the inlet. This is for a small LED addon that attaches to the end of the hose inlet.

For dental applications we do not recommend or offer the additional LED light that can go on the end of the hose, as these will get contaminated with biological matter and mercury particulate (if you perform amalgam removals).

So please tuck that wire inside the unit so that it is not in your way when you attach the hose.
