This is considered the best furnace filter because it can tackle common particles such as dust, mold, and more. These unhealthy air dwellers would otherwise be taking root in HVAC systems. It is relatively simple to install. Just take off the filter’s packaging, slide it into the filter track, and close the door of their purifier model. The filters feature a snug fit and self-sealing technology so that dirty air cannot escape around or through them.

This version is also amongst the best furnace air filters for people with allergies or asthma. Plus, it can last for up to twelve months before it needs to be replaced. This lifetime can be extended or reduced depending on interior air quality. Though the product does not technically come with a manufacturing warranty, it can be personally requested. Adding this step into the buying process takes some of the risks out of making this purchase. Overall, this is the best air filter for furnace use because of its ease of use, its extent of filtration, and the variety of pollutants it filters for. It might be a good place to start for those searching for an alternative to Filtrete furnace filters.

PROS:
  • Filters for many different types of irritants
  • Ideal for households with allergies or asthma
  • Can last up to twelve months
  • Available in value packs
  • Super simple to replace and change
  • Optional warranty
CONS:
  • None

Customers’ Reviews:

“I was surprised at how easy it was to install this into my system. We have some construction going on, and I’m honestly shocked every time I check on the filter to see how much pollution it has kept out of my house. I’d recommend it to anyone.”

“I especially love this filter for its ability to stop smells from traveling around my home. My husband loves to cook seafood, but the rest of us hate the smell. Now when he cooks, you cannot even tell unless you’re in the kitchen! It’s that good!”

“I’ve been buying this for my house for the past twenty years. Half of my home is underground, and it really keeps mildew and mold issues at a minimum. Plus, even though we have several pets in our house, their hair doesn’t seem to clog the products.”

Filtrete Micro Allergen Defense (16x20x1) | Exclusive Technology for an Impressive Clean

Best Furnace Filters for Your Home in 2020

This Filtrete Micro Allergen Defense air filter might be a good option for those seeking the best furnace air filter for allergies. It does not have the typical design that other units have. This one combines pleating with a protective diamond encasing. These units can be purchased in packs of two, and they come for a great value. It claims to work better than other washable and fiber-glass units. Users should just note that these filters have a shorter lifetime of 90 days for one-inch filters such as this one though.

One cool thing this manufacturer offers as an added bonus is a remind program to let owners know when to change their filter. Keeping a dirty filter in an HVAC system can actually be worse than having no filter at all. It will make it harder for air to flow through the system, and it will also blow some of the pollutants from the filter into the air.

This product has a relatively high MPR of 1000. That means that it can filter more microparticles than some of the other best furnace filters. Whether it is dust, pollen, or pet dander passing through an HVAC system, it will get trapped by this sheet. To install it, buyers should first remember to remove the plastic that the filter comes wrapped up in. Then, there will be arrows on the top of the unit showing which direction it should be faced. Depending on whether it is being placed into a central unit or into a wall, it will either be slid sideways into place on a track or placed vertically in the wall slot. Then, it can pretty much be forgotten about until it is time for a change.

  • Product
PROS:
  • Works for both wall or central unit use
  • Eliminates a wide variety of pollutants
  • Can sign up for changing reminders
  • Great overall value
CONS:
  • One-inch filters will not last more than 90 days

Customers’ Reviews:

“I bought this after reading its air filter ratings, and I am 100% happy with the quality I have received. I love that it comes in a two-pack and can be bought both online and in-store. It’s also super easy to install thanks to its helpful arrows.”

“I asked my friend, “what is the best furnace filter?” and this is the first one she mentioned. I bought it hoping it would take care of the allergens that consume my house every Spring and drive my family and me crazy. There is a lot less sneezing going on now.”

“My house is an extremely old, beautiful, and dusty Victorian. I love the house, but I use to hate dusting daily. I bought this hoping that it would reduce the airborne dust caused by our heating and it has worked so well. I only dust monthly now.”

Filtrete UR01 Healthy Living 2-Pack | High MPR for Extra-Fine Filtering

Best Furnace Filters for Your Home in 2020

The Filtrete UR01 finds a good balance between good price and performance. It is a product with a 1500 microparticle rating, meaning it can filter even the smallest of air particles. In fact, it is so good, it will trap particles as small as 0.3 to 1 microns in size. This is a similar capability of HEPA filters and other great products. For those with really sensitive allergies or asthma, this might be a good place to start. It traps all sorts of irritants that would otherwise trigger these issues, such as dust and dust mites, mold spores, and lint.

These filters will last a buyer about 3 months before it needs to be switched out for a clean one. Filtrete is a widely respected brand that uses a unique 3-in-1 3M technology in their products. This technology enables it to trap large amounts of particles but helps stop collecting pollution from negatively affecting airflow.

This unit also utilizes electrostatic technology. It works by actually attracting irritants almost like a magnet. It can even help catch bacteria and other viruses. This feature is helpful because even if a sick person stays quarantined in their room all day, HVAC systems can still transport their illness all over an entire house. This filter will stop that transportation and better protect the health of a home’s inhabitants. For those with large families where someone is always getting sick, this could be a good option.

  • Product
PROS:
  • Captures particles as small as 0.3 to 1.0 microns
  • Can trap bacteria and viruses
  • Uses electrostatic technology
  • Easy to replace
CONS:
  • Need to be replaced every 90 days

Customers’ Reviews:

“I’ve tried a bunch of different filters, but this one is probably my favorite. I think that this Filtrete Ultra Allergen product is the best at preventing the pressure from dropping in my HVAC system. It keeps the system efficient and my home as warm as possible in the winter.”

“I live in Georgia where there are pretty much allergens in the air 24/7. Despite my best efforts, they always work their way into my home. I decided to buy this product instead of an air purifier to see if it would help, and it has so much!”

“I think that this is the best filter for furnace use. I live in northern Canada where I like to use my heater almost year-round. As one can imagine, this can get pretty dusty. This filter takes care of those problems though, and it’s very easy to use.”

Filtrete Allergen Defense (16x25x4) | Lasts Longer Thanks to Thickness

Best Furnace Filters for Your Home in 2020

This version of the Filtrete Allergen Defense is similar to the one listed as #2. It catches similar pollutants that may irritate allergies or asthma. It differs in that it is much thicker. One-inch filters only last the user living in an average home about 90 days, equating to three months. This option, on the other hand, is four inches this. This added thickness extends the life of the product. Instead of three months, it will last buyers about twelve months, which is nearly four times as long! Like other Filtrete products, it comes with a reminding service that notifies users when it is time to switch out their dirty unit for a new clean one.

This has a microparticle performance rating of 1000. While it is designed to fit some types of cleaners such as the Honeywell Trion Air Bear, it can also be placed directly into a wall depending on its user’s needs. Its versatility and focus on preventing allergy and asthma triggers might make it a good option for people living in climates with several seasonal changes per year. It may also be a good choice for those that do not want to have to change their unit out frequently.

  • Product
PROS:
  • Long-lasting lifetime
  • Simple to install
  • Change reminder programs
  • Catches lots of different airborne pollutants
CONS:
  • Will not trap bacteria and viruses

Best Furnace Filters for Your Home in 2020

This Nordic Pure has been widely recognized as one of the best air filters for furnace usage thanks to the unit’s material. It is not only hypoallergenic but also antimicrobial.

AIRx MERV 8 Dust Filter(16x20x1) | Best Furnace Filters for Dust

Best Furnace Filters for Your Home in 2020

These AIRx MERV filters for dust control will suit buyers who are glad to keep things basic. This product is regarded as the best furnace filter for dust control because has the elements it needs to eliminate large pollutants like dust, but not much more. Because this unit does not have to filter for finer particles, it will allow air to pass through its fabric quicker. This means that when a user is running their heating or air conditioning, this filter will not be slowing down their airflow and wasting their electricity. They will also eliminate the bigger particles that would otherwise clog and potentially damage an HVAC system.

The manufacturers recommend that these units be replaced every two months or so. The product comes in packs of six to hypothetically get a user through an entire year before they would need to buy more replacements. To get the best results though, the units should probably be replaced every month, especially in homes that are more dusty than average or are near ongoing construction. Ultimately, this product is ideal for people who live in homes without mold, bacteria, or smoke problems, and are looking for a simple purchase to help their systems stay a bit cleaner.

AIRx MERV 11 Allergy Filter (16x20x1) | Best Value Option for Allergies

Best Furnace Filters for Your Home in 2020

This AIRx MERV 11 filter is extremely similar to the above MERV 8 option. It can be told apart by its stark red packaging. The only major difference is its ability to filter for smaller particles.

In addition to being able to capture everything that the MERV 8 can, it also filters for things like mold and stubborn smoke–common types of particles that irritate allergies. That being said, it still features optimally-placed pleating and will not decrease airflow too much. This keeps it a decent energy efficiency choice.

  • Product
PROS:
  • Great value option
  • Filters for more than the AIRx Dust
CONS:
  • Less energy-efficient than lower MERV options

Buyer’s Guide

Wondering, “what are the best furnace filters of 2020?” Or perhaps, “what is the best furnace filter for allergies?” Reading a furnace air filter review such as this one is a good place to start. However, it is also important for consumers to understand the terms they may come across during their search. One common one is MERV, which is arguably the most common rating method. While MERV can be rated on a scale of 1-20, you’ll typically see a rating of 8, 12 or 16. Higher ratings are able to trap finer pollution particles. Another important term to know is MPR, which is more common among higher-performing units. Like MERV, the higher the number, the better.

When purchasing replacement filters, versatility and lifetime should also be considered. Keep an eye out for products that can only be used with specific systems. Also, if possible, choose thicker filters that have to be replaced less often. It is a pain to have to remember to replace filters on a monthly basis or order new ones all the time. However, dirty filters can slow a person’s airflow and increase their electric bills. Those who want to think about their filters as little as possible should seek ones that require less maintenance. Otherwise, they will find themselves wasting energy and having trouble maintaining comfortable temperatures in their homes.

Overall, the best furnace filters for home usage depend on the buyer’s needs and preferences. For example, a buyer may not have allergies and therefore can buy cheaper filter replacements with a lower MERV or MPR rating such as a Clean Living basic product. At the same time, someone could live in a wildfire area or have bad asthma and require a high-tech filtrete smart filter to save themselves, their families, or coworkers from potentially harmful side effects. The answer to “what is the best furnace filter?” therefore entirely depends on the buyer. Sometimes, the #10 product on a list may suit an individual’s needs better than a pricier #1 option.
