Why Everest's Sub-Micron Air Filters are a Game-Changer for Indoor Air Quality

Indoor air pollution is a major health concern, with the Environmental Protection Agency (EPA) reporting that indoor air can be up to five times more polluted than outdoor air. Poor indoor air quality can lead to a variety of health problems, including respiratory issues, allergies, and headaches. In addition, COVID-19 has highlighted the importance of proper ventilation and air filtration to prevent the spread of airborne pathogens.

Luckily, there are solutions available to improve indoor air quality, including air filtration systems. Everest's sub-micron air filters, in particular, are a game-changer in the world of indoor air quality. In this article, we'll explore what makes these filters so unique and effective.

The Science Behind Sub-Micron Air Filters


First, it's important to understand what sub-micron air filters are and how they work. As their name suggests, sub-micron filters capture particles that are smaller than one micron in size. To put that in perspective, a human hair is roughly 50 microns in diameter. These tiny particles include allergens, bacteria, viruses, and other harmful pollutants that can cause respiratory issues.

Everest's sub-micron filters are made from advanced synthetic fibers that create a dense and uniform web. This web is then electrostatically charged to attract and capture even the smallest particles. The result is an air filter that is capable of capturing 99.97% of particles as small as 0.1 microns.

According to the Centers for Disease Control and Prevention (CDC), COVID-19 is primarily spread through respiratory droplets, but it can also be spread through airborne transmission. In fact, recent studies have shown that the virus can remain suspended in the air for hours, making proper ventilation and air filtration crucial to preventing the spread of COVID-19 indoors.

The Benefits of Sub-Micron Air Filters


Not only do sub-micron air filters capture harmful particles, but they also provide a range of other benefits. These benefits include:

  1. Improved Indoor Air Quality: Sub-micron air filters remove harmful pollutants and allergens from the air, improving indoor air quality and reducing the risk of respiratory issues.

  2. Better HVAC System Performance: When HVAC systems are fitted with sub-micron air filters, they perform more efficiently, which can lead to lower energy costs and reduced maintenance.

  3. Extended Lifespan: Sub-micron air filters are designed to last longer than traditional filters, reducing the need for frequent replacements and lowering costs over time.

A smart thermostat can help regulate indoor air quality by monitoring temperature and humidity levels, as well as adjusting the HVAC system to provide optimal ventilation.

How to Choose the Right Sub-Micron Air Filter


When it comes to choosing the right sub-micron air filter, there are a few factors to consider. These include:

  1. MERV Rating: MERV stands for Minimum Efficiency Reporting Value, and it measures the effectiveness of air filters. The higher the MERV rating, the better the filter's performance.

  2. Compatibility: Sub-micron air filters come in a variety of sizes and shapes, so it's important to choose one that is compatible with your HVAC system.

  3. Airflow Restriction: Some sub-micron air filters can restrict airflow, which can cause HVAC systems to work harder and use more energy. It's important to choose a filter that allows for proper airflow.

An indoor air quality monitor can help you track the effectiveness of your sub-micron air filter and provide real-time data on the quality of the air in your home or office.

Sub-micron air filters are a game-changer for indoor air quality. They are capable of capturing tiny particles that traditional air filters can't, making them more effective at improving indoor air quality and reducing the risk of respiratory issues. In addition, sub-micron filters provide a range of other benefits, including improved HVAC system performance and extended lifespan.


When choosing a sub-micron air filter, it's important to consider factors like the MERV rating, compatibility, and airflow restriction. By investing in a sub-micron air filter, you can breathe easy knowing that you're doing your part to improve indoor air quality and protect your health.
