Here we are going to talk about Honeywell FC100A1037 Air filter. This is a merv 11 filter and it measures 20 bz 25 by 5 inches.

This is one of the best brands out there, and the quality of production is better than with other brands. What we really liked is that the frame is stronger than the substitute brands and it doesn’t deform under pressure or moisture from the air.

What is a MERV 11 Filter?

MERV (Minimum Efficiency Rating Value) is an industry standard designed to enable comparing filters from different manufacturers. It also lays down a set of testing protocols to measure performance on air particulates with nominal sizes from 0.3 to 10 microns.

MERV was developed by ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers).

The scale goes from 1 to 20. 1 means the lowest efficiency, while 20 indicates the highest one. Each MERV rating has its own pre-defined size range of air particles and its own percentage of captured particles. (Check the full MERV rating chart here)

For example, Honeywell FC100A1037, as a MERV 11 filter, captures airborne particles from 1 to 10 microns. Being a pleated filter, it has a superior efficiency and air filtration versus the non-pleated filters.

What is it Good for?

This replacement filter is capable of filtering out pet dander, pollen, bacteria, dust, dust mites, lint, and mold.

What Unit You Can Use It With?

This is a replacement for the Honeywell whole house air cleaner. It can be used with Honeywell 20X25, 25X20, 25X22, F100 Media Air Cleaners.

In the Media Air Cleaner, for example, this is the main heart of the system. It’s one of the most important parts you would have in a system where you put in an air conditioning or a furnace in your home.

What it does is pretty basic. Historically we want to refer to this as an immediate air cleaner. This 5 inch wide air filter protects the furnace and the air quality in your home. It can last in there up to 12 months.

It makes sure not dust or dirt gets by in your living space. It prevents all pollution from happening. Once the predetermined period of operation is over, there is no dilemma, you should throw it away.

The cost value of it is what you would spend on a cheap filter every month and yet it

protects you really well, as well as your home furnace.

With this 5 inches wide air filter, the plates are much wider and the filter can take more air flow through it. So it makes a big difference on the quality. Sadly, people are not as aware as they could be, that they really need these filters.

Honeywell FC100A1037 Efficiency

For maximum efficiency Honeywell recommends replacing it every 12 months. That is, if you want to keep your air really clean to put bacteria, pet dander, allergens, mold out of your air.

This filter comes in multipacks, of 2 and 5.

The inside of these filters are paper for the most part. Even if the filter is not an original Honeywell. The substitute, however, may have less glue material, or be of lesser quality.

Make sure the replacement is built from water resistant frame (for example, galvanized rust resistant wire), that is, if you are going to use it in humid conditions.
