When air filters are designed, they’re assigned a MERV rating. MERV stands for Maximum Efficiency Reporting Value. It’s a valuable statistic that measures how well a filter can capture particles in the air. If you’re wondering where to start, take this guide for a spin. You’ll need to learn all about MERV first, so let the training begin.
Understanding the Value of an Air Filter
The MERV system can range from one to 16 or higher. A high rating equals the best value. Any filter that has a rating of 16 or above can easily trap smaller particles. A filter that has a lower rating will not be able to trap microscopic particles, but it will be able to capture everything else.
HEPA Filters – MERV Rating of 17
HEPA filters are best for allergy suffers. They’re highly durable, but they are not indestructible. When they’re past their prime, they will need to be replaced.
UV Filters – MERV Rating of 11
UV filters are great for the winter season. Unlike other filters, these filters can destroy bacteria and viruses in a home.
Electrostatic Filters – MERV Rating From 8 to 10
An electrostatic filter attacks dust particles with static electricity. When contaminates are nearby, it produces a charge in an instant. Then, as air moves through the filter, the charge is slowly released.
Washable Filters – MERV Rating from 1 to 4
A washable filter costs more than most filters, but it’s worth buying because it will pay for itself over and over again. With this filter, you’ll never need to buy regular replacements. When it gets dirty, you can easily wash it in tap water and reuse it.
More Filters to Consider
In addition to these filters, many companies also make fiberglass filters and pleated varieties. Fiberglass filters have a MERV rating that ranges from one to three, and pleated filters will usually have a MERV rating of five or higher.
