Top-Rated Furnace Filters for Optimal HVAC Performance

Top-Rated Furnace Filters for Optimal HVAC Performance

In order to improve the quality of the air in your home, it’s a good idea to install a furnace filter that will keep your HVAC ductwork clean and capture all dirt, pollen, dust and more such particles that would usually flow freely through your HVAC system and get inside your house.

Aside from installing permanent filter furnaces, you also need to replace the filter regularly.

How often that has to happen depends on how old the HVAC system is and the quality of the air around you.

However, as a general rule, replacing a furnace’s air filter every three months or so should be more than enough to not only improve air quality but also keep the furnace from malfunctioning and reduce energy costs!

In other words, replacing the filter with every changing season will ensure that it will not get clogged with things like pet hair, dust and other such airborne particles that could really shorten your furnace’s life otherwise.

At the same time, it’s worth mentioning that not everyone knows much about this kind of thing which is why this guide is here to teach you all the details, including how to choose the best furnace filters and more!

There are many options on the market as well, making it really hard to choose exactly what you may need and tell between good and bad filters.

One thing to take into consideration is whether or not the filter of your choice is even compatible with HVAC systems and furnace brands.

Furthermore, the best ones are those that can filter out as many particles and contaminants as possible and those that promise a long lifespan so you can get a lot of use out of your filter before you need to change it again.

That being said, while most of them last for 2 to 3 months, you can find some that last for more than a year at a time as well, making this type of filter a really good choice for those who are looking for something more convenient.

There are even some special features you can enjoy such as arrows placed on the frame in order to direct easier placement, odor control, airflow, HEPA filters.

Some of them come with Bluetooth capability as well, making the filters even more convenient!


It should be known that filters come in all kinds of sizes so pay attention to such specifications when purchasing them so you can be sure they’re compatible with your furnace.

The thickness varies as well, from 1 to 5 inches and as you can imagine, the thicker it is, the more and smaller particles it will be able to block.

If you’re thinking of getting a thicker option, make sure to check the furnace’s manual since not all of them fit a thicker filter.

After all, the thicker the filter, the harder the furnace needs to work to pull the air through it.

Disposable v. Washable

As mentioned before, filters usually need to be changed regularly but there are also other options for you such as washable filters.

While the disposable ones are lightweight and quite accessible, the reusable ones can be cleaned at home and feature a heavier aluminum frame with electrostatic fibers.

The washable ones may last you for several years depending on the brand but you need to keep in mind that they need to get washed in a specific way such as separating the filter into layers to clean them one by one.

Before reinstalling the washable filter, ensure that it is completely dry in order to keep mold from forming.

Many people go for disposable filters, however, since they are so convenient and easy to use.


One of the most efficient options is represented by high-efficiency particulate air filters that can block up to 99.7 percent of all airborne particles that are at least 0.3 microns in size.

Unfortunately, however, these are not readily available in sizes that fit most standard furnaces.

They are really dense as well, reducing airflow into the furnace significantly, which is why they are usually used only in commercial spaces or hospitals.

MERV Rating 

MERV means “efficiency reporting value” and it’s based on density.

The scale runs between 1 and 20, the filters in the 6-12 range being meant for residential use.

One thing to remember is that denser filters are able to block more particles but they will clog quicker as well, which means you’ll need to change them more frequently.

Once again, consult the furnace’s manual as it should specify the rating best suited to your particular unit, which is obviously really useful if you want to make sure you’re buying the right product.

All that being said, now that you have all the basic knowledge to ensure that you’ll be making an informed decision, in order to make your purchase of furnace filters even easier and straightforward, we have prepared a list of some of the best products on the market!

They are featured in no particular order so you can choose the most suitable one for your unique needs.
