Know about FPR, MERV, and MPR Rating

Filters are one of the essential things to maintain the efficiency of the HVAC system. While you are going to purchase an HVAC system you should always ask for a Cotton filter cloth or another type of filter material rating that can be inserted into the HVAC system.

The filter is responsible to maintain the fresh air flow inside the home. The efficiency level of the filter is measured through a standard or rating. The filter can be of FPR, MERV, or MPR.

Types of HVAC filter rating

MERV rating

All the standards are defined by the industry. MERV is one of them. MERV is a short name for minimum efficiency reporting value. This factor defines the value and specifications of the filter. There is an authority known as The American Society of Heating, refrigerating, and air-conditioning engineers proposed this standard and followed by more than 130+ countries.

MPR rating

3M is a prestigious organization. It is famous for innovative products. The development team is great and they put a lot of effort to make the best quality of products. MPR Rating is developed for the filter by 3M.

3M is involved in the production and development of deodorant, hygiene, and other medical care products. MPR is defined as Microparticle Performance Rating. It is different from MERV and FPR.

FPR rating

Filter performance rating is known as FPR. Home Depot designs its products by following this standard or rating. They are the developers of this standard. FPR is similar to MERV filters in many aspects.

All these filters are defined to measure the efficiency of the filter. All are best at their levels. You might be confused about which one you should purchase.

MERV rating is approved by the international authority as filter rating is different from one another so as their sizes. Before finalizing any filter you should check both the standard and size. MERV rating starts from 0 and goes up, higher rating encourages higher efficiency and better airflow of the indoor atmosphere.

You can purchase these filters online and offline from any filter manufacturer. You can read the rating reviews of different customers. So you can get satisfied with the functionalities and properties of each one and make your decision better.

For MERV 8 rating, most of the customers look for the 14x18x1, 14x14x1, 16x20x1, 16x25x1, 20x30x1, 20x25x1etc. Filters are categorized as a 1-inch filter, 2-inch filter, 4-inch filter. Apart from this, many other customized sizes are available at the place of the filter manufacturer.
