Air Filters

Which filter is right for you?

Proper air filter maintenance is the key to a healthy home, and ensuring your heating and air system works both effectively and efficiently.

A Duststop Air Filter is the perfect solution for your air filtration needs. By using our air filters in your system, you are ensuring cleaner, healthier, and fresher air. A clean air filter means you are not circulating dust, dust mites, pollen and other small particles in the air, letting you live in a clean and healthier home. Changing your air filter regularly will also ensure longevity of your HVAC system – saving you thousands in potential repair and replacement costs. A dirty air filter will also use more energy than a clean one, creating a higher electricity bill. As such, by keeping your air filter clean, you can save up to 15% on utility costs.


What Does MERV Mean to me?

Minimum Effeciency Reporting Value (MERV) ratings are used to rate the ability of an air cleaner filter to remove dust from the air as it passes through the filter. MERV is a standard used to measure the overall efficiency of a filter. The MERV scale ranges from 1 to 16, and measures a filter’s ability to remove particles from .30 to 10 microns in size. To give you an idea of the scale of a micron, 100 microns is about the thickness of a human hair. Filters with higher ratings not only remove more particles from the air, they also remove smaller particles.

MERV ratings are determined by adding particles of varying sizes into a controlled testing environment. The particles are added upstream of the test filter and a laser particle counter samples the air before it enters the filter and after it leaves the filter. The two particle counts are compared to calculate the Particle Size Efficiency of the tested filter. Once this is determined, a MERV Parameters chart is used to determine the MERV rating.
