Have you ever noticed the MERV rating on your AC filters when you replaced them? If you ever take a close look, you will see there’s a MERV rating that has significant implications. MERV mainly stands for ‘Minimum Efficiency Reporting Value,’ which indicates the efficiency of the filters in removing particles that are present in the air. Higher the MERV rating, better the efficiency of filters in catching particles from air.
But there’s a different side of the story as well. The higher the MERV rating, the greater is the force needed to push air through the filter. Since the MERV rating also indicates the density of filtration material, it is essential to have a robust AC unit that can push air through the filters.
Why Is It Essential For You to Find the MERV Rating?
As far as the types of filter are concerned, there are several types to fit for individual AC units. The moment you choose filters with a too high MERV rating for the residential AC units, it gets a similar reaction to using the dust-clogged filters. Under similar conditions of using dust clogged filters, the air struggles to push through putting stress on the fan and other components. Hence, it is evident for them to have more than standard wear and tear leading to more service and repair at frequent intervals.
Does It All Depend On A Yes or No?
For a streamlined daily operation of the AC unit with lesser service and repairs, it is essential to know the maximum MERV limit for the unit installed. There’s no point stressing your AC components and put expensive repair works in line. Do you need more filtration than what is installed now? Are there asthma patients in your home? Do you live in an area which is primarily dusty and dry letting more allergen flow in? If the answer to any of these questions is assertive, take a sigh of relief and install filters with higher MERV ratings.
Knowing the Capability of Multiple MERV Rating
Generally the MERV ratings are scaled in between 1-20. Read out to understand what the filters of multiple MERV ranges are capable of doing before installing one.
- MERV 1-4 – The filters with MERV rating 1-4 catch larger particles like dust, pollen, insects, mites, and also carpet fibers. Residential systems are the best place to use these filters.
- MERV 5-8 – Mainly designed for the commercial settings, these filters are even installed in some residences which are in dustier locations. Finer dust particles and aerosol spray particles are generally caught with these high-end filters.
- MERV 9-12 – These filters are seldom seen to be used in residential settings for they have been designed for pathological laboratories. Whether it is the welding fumes, larger bacteria or any kinds of automotive emissions, these filters can catch anything.
- MERV 13-16 – Surgical centers generally find these heavy-duty filters. You may even find them in the smoking lounges since these filters have the capability of catching a wide range of bacteria, oil droplets and fine particles which eventually leads to sneezing.
- MERV 17-20 – This is the highest range available for the filters and is mainly used in places which are stuffed with sensitive electronics. However minute the smoke particle be, these filters can catch anything and everything.
