Air filters are measured, evaluated, and rated using a variety of data. Understanding and comparing these figures is an important part of comparison-shopping for filters. One key element you want to look for in a high quality residential filter is a rating of about MERV 8 or higher.
MERV stands for minimum efficiency reporting value, and its scale is used to measure a filter’s poorest performance levels when filtering the smallest particles. The scale ranges from 1 to 16, with 1 being the worst performance and 16 being the best.
Choosing an electrostatic air filter with a MERV rating of 6 to 8 is a good way to separate the filters that aren’t worth your time from the rest. Although a 6 or 8 out of 16 doesn’t sound that great, remember that MERV ratings signify the worst-case performance of any given filter. With regular cleaning and care, you won’t have to worry about ever getting such poor performance out of your filter. Still, MERV figures can reveal much about the quality and sophistication of any given filter.
Our customers love to tell us how much more convenient it is to have a washable, reusable filter in their HVAC systems. Not having to go out to buy disposable filters has always been one of the things our customers love best about electrostatic air filter ownership. But there is another very important reason why many of them have switched to our products.
The components used in the construction of most disposable filters take a very long time to break down and biodegrade completely. With most US home owners still using disposable filters and replacing them at least every three months, that places a huge burden on landfills. You can be a part of an eco-friendly solution by choosing a high quality MERV 8 filter on our site today. You'll receive better indoor air quality, you'll save hundreds of dollars in the long run, and you'll have the satisfaction of knowing that you've dramatically reduced the size of your personal ecological footprint.
