The Role Of Air Purification Filters In Air Conditioners

Air purification filters are essential for improving indoor air quality in air conditioning units. These filters are designed to trap and eliminate a variety of pollutants, such as bacteria, mold spores, and fine particles. Some models even feature catechin filters, which are highly effective at removing harmful contaminants. Regularly cleaning and replacing these filters is important to maintain their efficiency.

It’s worth noting that using aftermarket air purifying filters for air conditioners may not have undergone thorough testing with all brands. In addition, using non-genuine parts can decrease performance and void warranties. To ensure optimal air purification and to uphold the warranty of your air conditioning unit, it is always advisable to stick to manufacturer-recommended filters and replacement procedures.

The Effectiveness Of Different Air Filter Types

When it comes to air filters in air conditioning units, their effectiveness largely depends on the type of filter and its MERV (Minimum Efficiency Reporting Value) rating. Filters in air conditioners should generally trap larger airborne pollutants, but their ability to capture smaller particles and viruses may vary.

The Environmental Protection Agency (EPA) recommends upgrading HVAC filters to a MERV 13 rating, as these filters can effectively trap smaller particles, including viruses. However, it is important to note that not all air conditioners, especially portable air conditioners and window units, can be upgraded without modification. Upgrading to a higher-efficiency filter may also decrease an air conditioner’s cooling ability.

It is important to keep in mind that air conditioner filters are only effective when the air conditioner is running, which is usually less than 25% of the day. Neglecting to clean and perform maintenance on air conditioners can lead to clogged filters, which can block airflow and reintroduce pollutants into indoor air. Regular cleaning and maintenance of air conditioning units are essential to ensure optimal air filtration and prevent the release of pollutants into the air.
