There are plenty of air filters for home ac units, but not all are able to trap tiny particles. You can find inexpensive, disposable air filters under $5, and there are also some that are closer to $100. You don’t have to spend a lot of money on the best HVAC filters, but you also don’t want the cheapest ones. Every time you open a door or window, you’re letting airborne particles in.
In addition, these filters are easy to install and equally easy to replace. They are also electrostatically charged hence can eliminate both positively and negatively charged airborne contaminants. These makes them ideal for tackling lint, dust, pollen, smoke, bacteria, viruses, pet dander, sneeze debris and cough debris. They are also electrostatically charged hence more efficient at filtration than non-electrostatic models. Besides, they are ideal for HVAC, furnace and air conditioner systems that require 20x20x1 replacement filters. Replacing your home’s air filter is one of the easiest and quickest repairs you can make to your air handling system.
Filtree Micro Allergen Defense AC Furnace Air Filter
Typically, if you need of a new air filter you go to the nearest hardware store, grocery store or wholesale warehouse and pick a filter that fits into your HVAC system. Picking out a random air filter, however, may not save you money nor improve your home’s indoor air quality. Just like other purchases you make, there are many factors that go into selecting the right air filter for your home. Our top recommendation for a furnace filter is the Filtrete Dust, Pollen, & Pet Dander Air Filter. With a MERV 8 rating, it’s a popular pick for general household use and reduces large particles in the air along with visible dust on flat surfaces. One very economical option is the Filtrete Clean Living Basic Dust Air Filter.
Changing your air filter regularly keeps your unit working as it should. While higher-rated filters can trap more particles, they can also put additional strain on your HVAC unit and cause your energy bill to go up. In most situations, a filter somewhere in the middle is more than sufficient.

By providing the model and serial number, a representative can tell you exactly the type of filter to purchase. So, while you might automatically think that a high-efficiency filter is the best choice, it may not be. Also, more commercial furnaces use true HEPA filters today in units to heat homes. Now that you have a much better understanding of the different types of furnace filters available, you need to know how to choose one of superior quality.
This filter has a MERV 5 rating, and is effective at keeping large particles from clogging your HVAC unit, as long as you regularly replace it at least every 90 days. You may notice that this furnace filter is significantly thicker than 90-day furnace filters. The extra depth is filled with pleated filter media to maximize the surface area available for capturing contaminants. This is an electrostatic filter, so the charge helps to draw in particles such as dust mites, mold, and smoke. Regularly replacing your AC filter with a high-quality option is a key strategy for reducing the amount of allergens in your home’s air supply. We recommend that allergy sufferers pick an air filter with a minimum MERV 9 rating, which places the filter in the "Superior Residential" category, according to ASHRAE standards.
Filtrete Dust, Pollen, & Pet Dander Air Filter
Usually packaged as a HEPA "system," these filters are the best of the best. VOCs, bacteria, viruses… HEPA filters capture nearly everything. Technically speaking, they trap particles as small as 0.3 microns in diameter, which is ridiculously small.
We do dismiss air purifiers that rely on ozone to “purify” the air. The theory is that ozone, which is highly reactive, neutralizes or breaks down pollutants. Setting aside the dubiousness of that claim, even low levels of ozone can be harmful .

And the need to frequently wash the plates—and, once a year, take the whole machine apart and give it a deep clean—sounds like a hassle rather than a selling point. We have long recommended running air purifiers on high for an hour and thereafter running them on the quiet or medium setting to create and maintain clean air in the home. At that fan speed, however, it’s far too loud for anyone to make conversation or watch TV nearby. Having that power available for an emergency situation, such as a nearby wildfire, is nice, but for everyday use you would probably want to run the machine on lower speeds and in a smaller room—350 square feet or so.
With Air Purifier, you can turn your home into an enjoyable and comfortable place to live without having to spend hours on the air cleaner.... But these are usually just filters with a rating of at least MERV 11, the rating where filters begin to catch the majority of particles that are the size of common allergens. There’s nothing uniquely anti-allergenic about these filters, and other filters with the same MERV rating should capture allergens just as well.
That doesn’t mean you have to buy the suggested product, but that it should be your first consideration. Additionally, it boasts the 3-in-1 technology from 3M, which allows the filter to draw in and trap irritants while simultaneously pushing clean air into the atmosphere. Another advantage is this furnace filter lasts between 6 and 12 months depending on your heating system and the degree of trapped particles. And using a washable air filter will absolutely help maintain the lifespan of your air handler.
This product has a MERV 8 rating, placing it in the "Better Residential" category for air filters. If you have issues breathing easily in your home, one the best air purifiers can help. These powerful machines are designed to filter pretty much all contaminants from the air, all without being too noisy or intruding on your decor. If you’re a pet owner, a quality air purifier can trap irritants and dander, and those with allergies or asthma should also consider adding one to their living space.
A few suggest every year, largely depending on the size of the HEPA filter and the prefiltration system. Under typical conditions, we recommend running air purifiers 24/7 on their highest “quiet” setting—which we define as 50 decibels or less. That generally means the medium setting on three-speed purifiers, or the high-medium setting on four-speed machines; specifically, that means avoiding the “automatic” setting that some purifiers come with. First, there’s no way to tell whether the sensor that these machines use to determine their automatic on/off cycles is working properly. Second, depending on what a manufacturer determines as “poor enough” air quality, an automatic setting may let the air in your home get quite laden with particulates before kicking the purifier on.
When CNET spoke with Richard Shaughnessy, director of indoor air research at the University of Tulsa, earlier in 2022, he said transmission of COVID usually happens due to close contact with an infected person. If you're sitting on a couch and chatting with someone who is infected, an air purifier across the room isn't going to remove all the harmful particles exhaled before they have a chance to reach you. Air purifiers do not affect the level of oxygen in the room in any way. Your air purifier is recirculating the air already in the room and cleaning it by passing it through a filter where microscopic, solid particles are removed. It is neither removing nor adding additional oxygen into the space. Air purifiers are also not the same as freestanding air conditioners, though the increased airflow from an air purifier may make the air in your home appreciably cooler.
The FilterBuy Dust Defense carries a MERV 8 rating and further enhances its ability to capture dust and other particles by using electrostatically charged filter media. Reducing household dust is a key benefit of using a high-quality air filter. By trapping small dust particles, rather than blowing them through your home’s ductwork, you should notice less surface dust.
Air filters differ in how effective they are at filtering contaminants from the air. When comparing a filter with a minimum filtration rating to an option with a high-level filter rating, there is a significant difference in the size of particles the filter captures. A furnace filter's media can be made from different materials.
