Frequently Asked Questions


Why are air purifiers important?

Most people spend around 90% of their time indoors, so Indoor Air Quality (IAQ) can significantly impact an individual's health and wellbeing. There are many adverse health conditions that can come from poor air quality.

How does an air purifier work?

At its most basic, an air purifier works by taking polluted air from a room and filtering it into clean air. It dilutes and displaces dirty air and introduces clean air into the room.

What does an air purifier filter out of the air?

Depending on the type of filter used, air purifiers can remove airborne particulates such as viruses, bacteria, mold, dust, pollen, odors, pet dander and other contaminants. These particulates are all different sizes, measured in microns.

How do you know if an air purifier will be effective?

There are two important measurements for air purifiers:

  • CFM, which measures airflow

  • MERV, which measures an air filter's ability to capture airborne particulates

CFM stands for Cubic Feet per Minute and measures how much air a fan can move both in volume and the rate in which it moves.

MERV stands for Minimum Efficiency Reporting Values and is a scale that goes from 1 to 16, with 16 representing the highest level of filtration. It was designed by ASHRAE – the American Society of Heating, Refrigerating and Air Conditioning Engineers. The higher the MERV rating of your filter, the cleaner the air will be at the output of the filter.

How do I compare different air purifiers?

Airflow and filtration are the two most important factors but other things to consider include power consumption, decibel level (loudness) and quality of components.


How many microns are Coronovirus particles?

Most airborne respiratory droplets range from 2.5-10 microns. However, the virus itself is typically <0.1 microns.

Certified HEPA filters remove all particulates, regardless of composition, with 99.97% or greater efficiency at ≥0.3 microns. The industry uses this 0.3 micron standard because 0.3 microns is the most difficult size particle to capture due to its larger size and the inertia it carries when traveling through the air. Smaller particles are more easily and efficiently captured.

Can air filtration really help keep my employees and customers safe?

Yes, it can help. The CDC and ASHRAE state that engineering controls offer critical protection in preparing workspaces and other trafficked areas against COVID-19. These controls start with installing HEPA filters and increasing air ventilation. The science shows that putting these engineering controls in place can reduce the risk of infection due to air contamination.

However, the engineering controls behind a Safe Air Zone should not be the only controls you implement to prevent the spread of COVID-19.

What is a Safe Air Zone?

A Safe Air Zone is any space where the air has been displaced, diluted and purified and is free of 99.97% of all airborne particulates at the output of the filter. We create these zones by utilizing Airbox Air Purifiers to bring clean room technology into any room you place them in.


What is a HEPA filter?

High Efficiency Particulate Air filters or HEPA filters are the most efficient and effective air filters on the planet. They actually EXCEED the MERV scale and are considered to register MERV of 17-20. This is a level of air purity found in clean rooms and pharmaceutical manufacturing facilities.

Certified HEPA filters can remove 99.97% of all 0.3 micron airborne particulates and more than 99.97% of larger and smaller particles.

Do all purifiers with HEPA filters perform the same?

Not necessarily. AIRBOX™ uses only Certified HEPA filters. But filters found in many consumer and commercial air filtration products are not acutally HEPA filters. Many consumer air purifiers do not meet the 99.97% efficiency of Certified HEPA filters and use "HEPA-like", "True HEPA" or other names to suggest they have HEPA filters when they do not. The Certified HEPA filters used by AIRBOX are the same filters used in advanced industrial cleanrooms to help protect sensitive manufacturing processes, prevent microbiological contamination in research labs and elimiinate infectious airborne contaminants in the healthcare sector.

How does the AIRBOX™ triple filtration system work?

The initial filter is carbon activated, which weeds out larger debris (down to 3 microns) while naturally absorbing organic compounds which can create bad odors. The second filter is treated with Microban®, an EPA registered antimicrobial agent which inhibits the growth of microbes and other living organizms that could cause degradation to the filter when captured. The third and final filter is the gold standard Certified HEPA filter, which removes particulates 0.3 microns and even smaller. Because the majority of particulates are larger, they are eliminated before reaching the Certified HEPA filter. This can expand the lifespan of the HEPA filter.


How often do Airbox filters need to be replaced?

It varies based on the size of the room and the application. The Certified HEPA filters can last for up to four years, the antimicrobial and carbon filters typically last for six months.

How many units will I need to create a Safe Air Zone?

We utilize several factors to determine appropriate coverage for you. These factors include:

  • Size of the space
  • Number of people in the room
  • Activity within the room
  • Layout of existing HVAC system
We will work with you to design a custom clean air solution for you and your business.

Will constantly runing the purifier burn out the fan motor and cost a lot of money?

Your AIRBOX is designed to run 24/7/365 and uses the highest quality fan in the world for this application. AIRBOX units typically consume less than 60 watts of power while operating in their energy efficiency zone. Energy efficiency doesn't mean less effective though. In this zone, over 15,000 cubic feet of Pure Air is produced every single hour of operation. At average power rates in the United Sates, 60 watts cost less than 20 cents per day or $73 per year.

Do you offer maintenance contracts?

Yes, we do. Our maintenance contracts include documentation supporting the continuing efficiency of your AIRBOX system. We have customizable options available and will be happy to discuss more details during our planning sessions with you.

Do you need protective gear to change the filters?

We follow ASHRAE recommendations to wear a mask, eye protection and gloves when changing filters and strongly recommend that if you change your own filters, you do too.
