Would you like to learn everything you need to know about air conditioner filters?
Air conditioner filters play a very essential role in the everyday functioning of an air conditioner. 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 what is known as 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 sufficient. These filters can keep out common allergens like pollen, spores, mold, most fibers, dog hair and cat hair.
Filters with higher MERV ratings are generally required in ACs installed in hospitals. These can keep out allergens like bacteria, viruses, smoke, etc.
2. Replaceable and washable 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:
Air conditioner filters should be replaced ever 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 the presence of pets can also determine how often you should change the filter.
Not changing filters will affect the air quality and your house will be clouded with particles that cause allergies and diseases. Also if your filter gets clogged up with too many particles, it could lead to more stress on the AC unit as 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 written in the user’s manual. Only purchase and use this filter. Using a filter that isn’t recommended could damage the AC unit.
This is everything you need to know about air conditioner filters. Make sure you read this article before purchasing or replacing one.
