AC Filters

Would you like to learn everything you need to know about air conditioner filters?

Air conditioner filters play a vital role in how an air conditioner functions. Their absence will definitely affect the performance of your AC unit.

Hence we have discussed everything you need to know about AC filters below.

1. MERV Rating:

Filters have a Minimum Efficiency Reporting Value (MERV) rating. It’s a scale which helps determine how effective a filter is. MERV ratings start from 1 and go on till 20. The higher the MERV rating, the more particles the filter will be able to strain out when the AC unit pulls in air. For most homes and offices a filter with a MERV rating between 1 and 12 should be enough. These filters can keep out common allergens. These include pollen, spores, mold, most fibers, dog hair and cat hair.
Filters with higher MERV ratings are often needed in ACs installed in hospitals. These can keep out allergens like bacteria, viruses, smoke, etc.


2. Replaceable and Washable AC Filters:

There are two kinds of air conditioner filters, replaceable and washable. Most air conditioning units will have the replaceable variety. Filters also come in various sizes.

3. Replacing Filters:

You should replace air conditioner filters every 4 weeks at least. If you use the AC more often you will need to replace them sooner. Other factors, like the area you live in and pets can also determine how often you should change the filter.
Not changing filters will affect the air quality. Your house will have tons of particles that cause allergies and diseases. If your filter gets clogged, it could lead to more stress on the AC unit. It will need to work harder to pull air in through the filter.

4. Always Use the Recommended Filter:

The type of filter you use (size, MERV rating, etc.) will be in the user’s manual. Only buy and use this filter. Using a filter that isn’t recommended could damage the AC unit.
