Furnace Filter Buying Guide

A furnace filter might not be an exciting item that adds a visual impact to your decor. But what it does is improve the air quality you and your family breathe.

It directly impacts health, and if not taken great care of, things can go another way around and can cause damage.

The filters were initially not designed and used to improve the air quality. They were used to protect the system installed in our homes.

But with the advancement of technology, filter quality improved and we are there with the filters that improve air quality.


Here size matters the most; in case you end up with a wrong-sized filter that does not fit with the furnace, there will be no use for it.

And if you install the wrong-sized filter, it bends over and would not be filtering the air as well as it should.

Air filter comes in variable sizes such as 16 by 20 inches, 20 by 20 inches and like that. Filter thickness varies from one inch to five inches.

The thicker the filter is, the more efficiently it will filter air. But you should check your furnace before buying a furnace filter.

Most of the furnace filters do not come with 5 inches thick filters as the furnace will have to do some extra work to pull air.

Rewash able or Disposable

Furnace comes in rewash able and disposable types. The disposable ones are lightweight, easy to use and once they get their job you can toss them off.

Rewash able filters can be used after washing them. They usually are made of a heavy aluminum frame with electrostatic fiber that makes them last longer.

There is an age even for a rewash able filter, after a specified period, you will have to dispose of it off.

Washing a filter is a job in itself. You have to separate them into parts, wash them one by one. And dry them off completely before reinstalling them.

Most of us think that once we install the system there is no need to change the filter. If you do not do that it can cause damage to the HVAC itself, it may burn the blower or fan installed in the HVAC.

And more importantly, this is going to have an impact on your health negatively.

MERV (Minimum Efficiency Reporting Value)

Furnace filters are given a Minimum Efficiency Reporting value considering their efficiency of blocking dust and airborne particles.

The higher the rating, the more an Air filter would be able to block contaminated Air. The rating is given from 1-20 numbers, most of the filters we see around in between 8-13 ratings.

And 6-12 range is designed for residential use. You must check your furnace system before you buy a filter with the MERV rating you like.

The system recommends a specified rated filter, and you should act upon it accordingly.


The environment is also a deciding factor that should be pondered upon when buying a filter.

For example, if you cook meals in homes, or do barbeque every weekend, or there is a wood firing place around, the thing you should check if, odor-absorbing or eliminating capacity of a filter.

In the same way, in humid environments, when it rains more than regular, mold build is the biggest issue, for that, you should buy a filter that protects against mold build-up.

Final Verdict

A furnace filter will surely improve the air quality indoors that is directly linked to you and your family’s health.

It blocks and removes the particulates that can trigger allergic reactions. Surely a top-rated air filter maintains a clean, and odor-free environment that perfectly aligns right with sensitive lungs and airways.

In this long guide, we have reviewed top Furnace Air filters. You can check them, behold their rating, and upon getting satisfied give any of them a shot.

One more thing, keep an eye if the air filter has reached its age. And change it frequently as per the recommendation of the experts.

FAQs About Furnace Filter

Can I use more than one filter in a Furnace?

Yes, if you have independent air conditioning and heating system installed in your home, you can use more than one filter.

For that event, you will have to check the specification of the furnace or Air conditioner, whether or not it allows installation of more than one filter in one system.

For someone with centralized heating and cooling system such as HVAC, there is only one filter that helps for cooling and heating at the same time.

For that you can’t install more than one filter in your Furnace, if you do, the blower or fan will have to do double work to push air.

Is It Safe To Use  A Furnace without Filter?

There could be two results for that; first, the system due to building up of dust and grime may burn out or crash, second you or your family face breathing issues.

As there is no filter installed, dust grimes and other contaminations are entering into your system and poured into your home as it is.

No filter means there is no filtration of dust, grimes, or pollen before pushing air into your home.

Which is MERV 8 or 11 better?

There is a rating given to every filter considering its efficiency to block contamination, dust, grime, pollen, and other microscopic microbes that is called MERV ( minimum efficiency reporting).

This rating gives a number to any filter upon its efficiency from 0-20. For residential places, it is considered that any filter should at least have 6-MERV.

11 MERV is better as it got the capability to block more contaminations than the 8 MERV rating.

But it is good to check your furnace before you install any filter or ponder upon MERV rating, and act upon it as per the recommendations.

What size air filter do you need?

First, measure the furnace space where you would be installing that filter. Measure in length, width, and depth in inches.

Then you can go out to buy a filter that fits right. Do not go without measuring or you will end up with a wrong-sized filter.
