  • Limited MPR 300 rating

Furnace filters catch dirt and debris that might otherwise find its way into your HVAC system, leading to part failure, dirty ducts, and worsened air quality. You should always have a furnace filter installed in your home, even if its an affordable, disposable furnace filter like the Filtrete Basic Dust and Lint Air Filter.

Designed to be quickly installed and easily disposed of after the filters 90-day lifecycle, this furnace filter captures particles between 3 and 10 microns in size. As the name suggests, the Filtrete Basic Dust and Lint Air Filter is best suited for reducing household dust, lint, and dust mite debris. It has a rather low MPR 300 rating, which means it wont capture as many microparticles as more advanced furnace filters. However, the MERV 5 rating qualifies this filter as a step-up from the most basic furnace filters available.

Selecting The Best Furnace Filter For Allergies

One of the best ways to protect yourself from the side effects of allergies is to have a good furnace air filter. However, the best furnace air filter for allergies is up to each individual person.

Theres no singular air filter that works the best for everyone. For example, many people like to have the disposable version because they provide a higher MERV rating. In addition, youll need to consider what allergens trigger your particular allergies.

For example, some people have allergies triggered by mold spores or pet dander. First, these allergies need a filter with a higher MERV number and can filter out small microscopic organisms and dust and lint.

If you live in an area with extreme climate conditions, youll also want to consider that too. Not all filters are ideal for all climates. Do some careful research to determine if the filter you want can handle the volume of allergens and the climate you reside in before you make a purchase.

Great Recycled Board Filter

The 16x16x1 pleated air filter is also one of the best HVAC air filters for allergies, and it is built to endure.

These air filters are non-washable and are intended to last for three months. They may be used in both the furnace and the air conditioner. For just a few bucks, you may keep your HVAC filters in place for months at a time.

For home usage, a MERV rating of 8 is great for hypoallergenic furnace filters. As a result, your indoor air quality improves, and youre able to enjoy the things to which youre allergic without having to deal with the symptoms of an allergy attack.

A Perfectly Good Hvac Filter: Nordic Pure Merv 12

*At the time of publishing, the price was $43.

Nordic Pures MERV 12 filters are not the only products that meet all our criteria, but they are perfectly good examples, and theyre usually competitively priced and easy to find online. We like that theyre genuinely MERV-certified, because unlike the proprietary ratings used by some bigger-name brands, the MERV criteria are publicly available. Being rated MERV 12, the Nordic Pures will remove at least 35 percent of particles in the 0.3-to-1.0-micron range, which includes bacteria and smoke at least 80 percent of 1.0-to-3.0-micron particles, which include fine dust and soot and at least 90 percent of larger pollen, dust, pet hair, and lint particles. Again, MERV stands for Minimum Efficiency Reporting Value, so this is the worst performance measured during third-party testing to the ASHRAE 52.2 standard. And again: the MERV test measures a single pass of polluted air through the filter. In your home, the air will continuously recirculate when your HVAC system is, leading to cumulatively greater filtration with each trip through the return registers.

Nordic Pure filters are mostly sold online, and the MERV 12s typically retail for a much lower price than competitorsabout $40 for a six-pack of 16-by-25-by-1-inch filters, or about $7 each . At the recommended three-month replacement cycle, a Nordic Pure can save you about $30 to $40 a year.

Two Other Filters That Should Do A Fine Job

Airpura H600

If you cant find Nordic Pure in your size, or if you prefer to buy and pick up a new filter in a store immediately, Honeywells FPR 9 filters and Filtretes MPR 1500 filters are similar, and theyre widely available at retail. . These filters perform on a similar level as the Nordic Pure MERV 12, they are well-reviewed by many owners, they come in a wide range of sizes, and the high likelihood that theyre in stock at a nearby hardware store is a big advantage if you need one ASAP.

We dont love that neither Honeywell or Filtrete is MERV-certified, but their proprietary ratings are reportedly equivalent to MERV 11 or 12. We couldnt find pressure-drop information on the Honeywell, so thats a possible concern. The Filtretes pressure drop is 0.22 inch, fractionally lower than the Nordic Pure MERV 12s at 0.24 inch. Data Filtrete shared with us indicates the the 1500 removed 54 percent of 0.3-to-1-micron particles in its own tests, versus a minimum of 35 percent for the MERV 12-certified Nordic Pure. On larger particles, the two filters performed very similarly.

Owen also offered a simple way to judge if its time for a swap: If you can get to your filter easily, one simple thing you can do is just go take a look. If you cant see the filter media anymore, its been in there too long. Change it!

The Microparticle Performance Rating Vs Merv Vs Fpr

The Microparticle Performance Rating or MPR is a rating scale created by Filtrete under the 3M company and it rates the filters ability to capture the smallest of airborne particles from the air .

These particles captured are microscopic, ranging in size from .3-1 micron in size.

The rating helps customers properly evaluate the ability of the Filtrete filtration. The higher the MPR rating, the better the filter is at capturing the smallest particulates.

The most common ratings for Filtrete filters are 300-1000 MPR but the top furnace filters for allergies are 1500-2800 MPR.

The American Society of Heating, Refrigerating and Air-Conditioning Engineers has a slightly different scale for filters called the MERV rating. This rating goes from 1-16, the higher the rating, the more effective the filter for .3-10 micrometers of particulate matter.

MERV 7 to 13 are almost as effective as true HEPA filters at removing allergens, with a much lower associated system and operating costs. This means that using high-quality filters can actually help your HVAC system perform with more efficiency and keep the inside of equipment from accumulating dust.

How Do I Choose The Best Air Purifier For Asthma And Allergies

In order to look for the best air purifier for allergies and asthma, you should spot the following:

  • Low noise level. Having a low noise air purifier can help you get some shuteye. If you are a light sleeper then youd best bet on a low noise unit so that you wont get distracted. After all, some people cant sleep with a running motor noise in their room.
  • True HEPA filter. Compared to a regular HEPA filter, the True HEPA filter can clean up to 99.97% of airborne particles, dust, allergens, pollen, and the like.
  • It is more powerful than your average air filter so it may have a better chance of clearing up your surroundings against particles that may trigger your allergy or asthma.

  • Activated carbon filter. Sometimes, smoke from fish and other sources could cause you to sneeze or have difficulty in breathing. An activated carbon filter does the job by eliminating or at least minimizing the number of smelly particles in the air.
  • Higher CFM or fan speeds. Having a faster CFM and fan speed can help to eliminate more allergens in the air, which can be ideal for those with asthma or allergies.
  • This would also be helpful if its hay fever season, where pollen counts could be massive in your area. Higher fan speed can move air much faster and thereby possibly helping you breathe better.

    How Big Is The Area Youd Like To Filter

    The amount of space in your room should also guide your selection. Check how many square feet a unit can handle when evaluating it.

    You can look for the clean air delivery rate to determine how many particles and square feet an air purifier can reach. For example, HEPA filters can clean the smallest particles like tobacco smoke and medium and large particles like dust and pollen out of the air and may have a high CADR.

    How Frequently Should You Run Your Air Purifier

    While the amount of time that an air purifier will take to improve the air quality of a given room varies, in general, you should run your air purifier at least a few hours per day. Youll want to make sure to run your air purifier at least once per day to ensure that you benefit most from it. You could also run your air purifier 24/7 but should note that this will use more power, and you may need to replace and/or clean the air purifiers filters more often.

    Is My Home Giving Me Allergies

    Air quality matters for good health and easeful breath. Often, what folks label as persistent colds and sniffles is actually a case of allergies. Whether its seasonal allergens, such as pollen, or home allergens, such as dust, dust mites, or pet dander, there are a lot of foreign objects swirling around in the air.

    Allergens accumulate naturally throughout the days, weeks, and months through no fault of the homeowner. If you have a pet, dander and fur will fly. Bits of fall goldenrod will waft in through open windows. Its all just a part of living. And living with these allergens over time can cause sensitivity, even in those who dont consider themselves to be allergy sufferers. For people with asthma, these air quality disturbances are easy to discern, and harder to manage. Thats why AC models with a focus on air purification are so helpful. Lets take a deeper dive.

    Air Purifier Buyer’s Guide

    Air purifiers are handily portable devices that combine the power of an internal filter with a fan to remove unwanted particles from the air in a designated room. The freshly purified air is then circulated back into the room. An air purifier can eliminate pollutants like wildfire smoke, pet dander, dust, pollen, and other toxins in the air of a specific room. Air purifiers are the opposite of an oil diffuser or humidifier, in that they remove particles from the indoor air instead of adding particles to the air. In fact, the Environmental Protection Agency reports that particular pollutants can be anywhere from 2-5 times more concentrated indoors than outdoors. So, an air purifier is clearly a worthwhile investment.

    In this guide, we review the different filter types built into air purifiers, as well as air purifiers that operate without filters and cutting-edge technology to sanitize the air. We also cover the particle removal process carried out by air purifiers, the different target pollutants of an air purifier, and the coverage, dimensions, and features of air purifiers.

    When Should I Get A New Purifier

    AF BEST Air Purifier for Asthma with HEPA & Active Carbon Filters for Allergies removal

    If youre finding that your air isnt as clean as youd like it to be or youve noticed an increase in allergic reactions, you might be thinking about buying a new air purifier. If this is the case, consider checking the filter first and make sure it doesnt need to be replaced.

    In most air purifiers, the filter does all the work, so if its not working at its usual capacity, the filter is probably to blame and not the purifier itself. However, if the mechanical hardware like the fan, control panel, or air quality sensors breaks down, youll want to get a new purifier.

    In addition, if the air purifier cant keep up in new and larger spaces, consider getting a larger purifier.
