ASKED QUESTIONS

Is Air Quality Guard added onto the HVAC system?


Air Quality Guard can be set up as an entirely separate system or integrated with the HVAC system. If set up to perform independently of the HVAC system, it is important to point out that it doesn't pose any significant challenge to the HVAC system as there is neither a net loss nor gain of air within your conditioned space. The HVAC system alone is insufficient for high level airborne contaminant removal, which is what our system excels at. Adding this as a standalone system to your office will bring cleanroom-level air cleaning technology to your practice.

In new construction and remodeling situations, we design a hybrid HVAC/Aerosol Solutions System to perform the "right way," working in unison to move air from areas of low contamination risk toward spaces of high contamination risk. When joined with the HVAC system in existing spaces, a reworking of the HVAC system is in order to correct the "wrong way" in which HVAC systems have been installed in dental offices for decades (i.e. moving air in the wrong direction) . Then, the two systems can be connected such that all air that comes out of a register in your office is cleanroom-level air only.




What filters does Air Quality Guard use?


Air Quality Guard utilizes a prefilter, an activated carbon filter for the removal of odors and gases (including Mercury vapors and Nitrous Oxide gas), and a powerful 99.99% HEPA filter​. The prefilters significantly prolong the life of the HEPA filter. These filters in combination mean virtually 100% of all pathogens, particles, and pollutants are removed from your office air on the first pass through the filters!




How much space does Air Quality Guard occupy?


​We designed the Air Quality Guard system to take up ZERO floor space! The arm is attached to the ceiling or wall at the ceiling level and folds up and out of the way when not needed. Intakes are placed in the ceilings of non-clinical rooms spaces. The fan and filtration housing are likewise placed in the ceiling. They are designed to occupy a 2'x4' ceiling tile space in drop-down ceilings and are readily adapted to drywall ceilings as well. Small ductwork segments connect the arms and ceiling intakes to the ultra quiet motor.




The aerosol extraction arms in the pictures look slightly different. Why is this?


Air Quality Guard is available with either 3" or 4" diameter arms. The standard size is 4". While both aerosol extraction arms are extremely potent at source capture of aerosols and splatter, the 4" arms are able to nearly double the airflow capacity of the 3" arms. So, you are seeing both arms depicted in the photos.




How much noise is generated by Air Quality Guard?


Air Quality Guard is exceptionally quiet! If operated at the recommended airflow velocities, each arm generates a whisper quiet 40-50 dB measured at 1 foot away. Patients either do not hear this noise or may hear a soothing white noise coming from the arm. The ceiling-mounted fan units generate a whisper quiet 40-50 dB, which sounds similar to air moving through registers.
