Why changing your air filter is so important.
If you are like most people, you aren’t thinking about your HVAC system until it stops functioning the way it should. Do you know one of the biggest sources of a system complication or failure? Clogged air filters.
When the filter becomes clogged, air cannot easily flow through the system. This causes the whole system to have to work harder to distribute heat or air where it is needed, which increases your utility bills since the air is running for longer.
If the air filter is clogged and cannot trap contaminants as it did before, those things can end up back in the air that everyone in your home is breathing. Immediate issues could include headaches, itchy eyes or throat, and dizziness. If the air filters are not changed and the issues continue, the long-term effects could be respiratory diseases and heart disease.
What our filters do and how they clean.
Our reusable HVAC air filters clean the air by using static electricity – a safe, naturally occurring phenomenon. An electrostatic charge is generated by air flowing through a maze of static prone fibres. Airborne particles are attracted and held by the static charge until released by washing.
They act as a barrier to prevent contaminants and other particles from circulating in the air, or from reaching sensitive parts of the system. Some of the common things that filters block are dust, pollen, lint, mold, hair, animal fur, bacteria, and more.


Don't just collect. Destory the widest range of pollutants.
Our Electrostatic filters have a different dust loading pattern of the electrostatic fibers. This unique characteristic improves air flow while providing maximum filtration.
The air you breathe contains many irritants such as pollen, dust, bacteria, mold spores, pet dander and smoke. Most of these particles are smaller than ten microns. Your air filter is an effective and efficient way to reduce the number of these particles in your air.
Arrestance is just a fancy word for filtering capacity. All of our filters come in the best and highest of arrestance – 94%. The 94% arrestance filter provides higher filtering capacity by trapping up to 94% of particles in the air. All 94% filters contain an EPA registered anti-microbial material to inhibit the mold and bacteria growth on the filter surface.
How to clean your reusable air filter.
Cleaning is quick and easy when cleaned as directed, your air filter will give you many years of trouble-free use. Failure to properly clean the filter may lessen filter effectiveness, and as with any air filter, it is possible for an excessive dirt buildup to cause air flow resistance sufficient to damage other ventilation components. Depending on your specific situation the filter should be cleaned every 4-6 weeks. Cleaning Instructions
- Simply remove the air filter.
- Flush with water in opposite direction of air flow
- Spray with cleaner to remove stubborn stains.
- Rinse thoroughly to remove remaining dirt.
- Drain excess water, let air dry, and reinstall.

MERV 8
MERV 8 filters help capture airborne particles and allergens between 3-10 microns in size. An ideal upgrade from standard disposable panel filters. MERV 8 air filters enhance the filtration efficiency in your home or office. Not only will these filters remove the dust, pollen, and lint in your home, but they will actively find and trap harmful pollutants like mold, preventing allergy and asthma triggers and promoting a healthy, safe environment.

MERV Rating Explained
The Minimum Efficiency Reporting Value, or MERV Ratings Chart, rates the effectiveness of air filters according to a measurement scale designed in 1987 by the American Society of Heating, Refrigerating and Air Conditioning Engineers. This illustrious group of experts created the chart in an effort to improve health, reduce costs and create more energy-efficient HVAC systems. However, the average homeowner often is unaware that such a chart exists, and if they are aware of it, they haven’t the slightest idea how to read it.
Bigger Is Not Always Better
The MERV Ratings Chart addresses the filter needs of all residential and commercial applications in HVAC. The chart addresses the fact that various applications have different filtering requirements. For example, a hospital needs a filter with a higher MERV rating than a residential window air conditioner due to the need for removing bacteria from the air. However, filters with a high MERV rating are not practical in central HVAC systems due to the large pressure drop caused by dense filters. Choosing a filter with the proper MERV rating is not only important for protecting the health of those who will inhabit the building, but also to guarantee that your HVAC system runs efficiently.
MERV Ratings Ranges
Simply explained, the MERV Ratings Chart provides information about which filters provide the best protection against various pollutants. Pollutants are measured in a range of 0.3 to 10 micrometers. Dust mites and cockroach debris, which no one really wants to think about as floating around their home, are rated at 10.0 micrometers or higher. Filters with a less obstructive filter can trap these larger particles, which is fine for many residential and general commercial applications. However, for those who suffer from asthma or are in areas where the air must be kept cleaner, such as laboratories, tighter filters are necessary to block smaller particle contaminants, such as lead dust, auto emissions and bacteria. To complicate matters even further, highly-rated filters are necessary in areas where significant contaminants exist, such as sea salt and smoke. These highly-rated filters are recommended for manufacturing applications.
