I Tested And Reviewed 6 Best Air Filters For Home Ac (2023)

I have been using the BNX furnace filters for a month now and I have to say, they have exceeded my expectations. Changing filters has always been a hassle for me, but with these filters, it's a breeze. The four pack comes individually wrapped, and the filters and frames feel sturdy and well-made.

One of the features I really appreciate is the clear labels on the filter. It makes it easy to install the filter correctly every time, without any guesswork. I have noticed that since using these filters, my air purifier has been working less hard. The orange and red settings on it come on much less frequently, indicating that the air quality has improved.

Although I don't have an exact air quality reading, I can see that the filter is doing its job. I have already noticed some wear on the filter, which means it's filtering out pollutants effectively. Despite filtering more pollutants, the air flow has not been restricted in any noticeable way.

One aspect that I really appreciate about these filters is that they are made in the US and from recycled cardboard. Not only does this support the local community, but it also contributes to a healthier environment.

Comparing these filters to the 3M Healthy Living filters, I have found that the BNX filters are just as effective, if not more so. They are priced at about half to two-thirds the price of the 3M filters, making them a more affordable option. The BNX filters have an arrow indicating the direction of airflow, making installation a piece of cake.

In terms of filtration capabilities, the BNX filters are on par with the 3M Healthy Living filters. They filter out dust, bacteria, smoke, and other pollutants effectively. There was only one minor difference in terms of what the filters didn't filter out, but it wasn't a concern for me.

The aesthetics of the filters are slightly different, with the 3M filters having more pleats and a mesh wire across the filter. The BNX filters have fewer pleats, but each pleat is perfectly spaced from the others thanks to the reinforced mesh wire.

I was initially skeptical about this filter, but decided to give it a try. After a few days, I did notice a change in the color of the filter from a vibrant pink to a dull pink or salmon-like color, as some others have mentioned. I decided to keep the filter in longer to see if it would turn yellow, as stated in the online description.

Around the one-month mark, I replaced the filter and it was indeed yellow throughout. Although I didn't receive any pamphlet or magnet as mentioned by other reviewers, I relied on the online description for instructions. For reference, my household includes 2 dogs, 2 rats, and 2 large cats, resulting in a lot of dander and allergens in the air. I also have 5 children, 2 of whom have severe allergies and are on the autism spectrum.

We are now on the second filter, which has been in use for about a week. It is still bright pink, and I must say, the difference in my AC unit is remarkable. Living in Arizona where temperatures can reach as high as 115/120 degrees, I used to keep the air conditioner set at 69 degrees to cool the house properly with the old filters. However, with this new filter, I can comfortably set it at 77 degrees. The AC unit doesn't have to work as hard, the air quality has improved significantly, and there are virtually no lingering odors in the house (although pet odors were never an issue for us, there used to be cooking and other smells that would linger).

I highly recommend this filter and will definitely be purchasing more from this company. It has made a noticeable difference in the air quality, cooling efficiency, and odor control in my home.

I have been using this air filter for quite some time now and I must say, it has been a game-changer. I found that placing it inside my air filter but outside of the HEPA part has been extremely effective in collecting large dust particles and preventing them from clogging up my HEPA filter. As a result, my HEPA filter lasts for several years, and all I have to do is vacuum it out twice a year and put it back together. This has saved me a fortune in filter replacements.

One of the things I really appreciate about this air filter is its ability to reduce TVOC (Total Volatile Organic Compounds) levels. I use a graphing air monitor to determine when the activated carbon is no longer effective at reducing TVOC below 600 ppb. I have compared it to other brands on Amazon that advertise similar specifications, and none of them have been able to maintain the TVOC levels as effectively as this product. It has proven to be a reliable solution for reducing TVOC, and I even use it above my car's cabin filter to reduce TVOC when driving.

In terms of practicality, this air filter has been a lifesaver for me. I live in a very old farmhouse, and every year I need to get filters for all the heat vents. The problem is, the filters never come in the right size, so I end up cutting them to fit. With this air filter, I was thrilled to find that it is one piece, which means there's no waste when I cut it to the desired size. Additionally, the charcoal filter is firm yet flexible, making it incredibly easy to install. It has made the whole process of replacing filters so much easier, and I have noticed a significant decrease in dust as well.

I also want to mention that this air filter has worked wonders for my box fans in windows. It has greatly reduced the amount of dust coming into my home, which has been a relief, especially considering my allergies.

However, I feel the need to caution against using this product for making small alcohol heaters. It is not labeled or designed for that purpose, and attempting to use it as such will result in it burning out quickly. So, it's best to stick to its intended use as an air filter.

Lastly, I have to mention the difficulty I have faced in finding filters for my various air purifiers. It seems that finding the right size and type of filters has been a challenge, but this carbon sheet has been a lifesaver. I was able to measure and cut the dimensions I needed for my older air cleaner, which I had been struggling to find filters for over a year. As soon as I inserted the carbon sheet, it immediately started working better. This product has been a blessing, as it has saved me from constantly searching for specific filters and has provided me with a long-lasting solution.

The air filter market faces two major challenges: price and performance. Firstly, prices for air filters are often marked up significantly, making them overpriced compared to their actual cost. Secondly, determining the quality and performance of replacement or knock-off filters can be difficult without using them for an extended period or conducting testing.

One notable seller in the market is Plumbing Planet, known for offering genuine Honeywell replacement filters. However, some sellers may offer substitutes instead, making it unclear what you will receive unless you contact them beforehand. If performance is your main concern, it is recommended to buy from Plumbing Planet to ensure you get the genuine item. However, if price is a higher priority, you may consider taking a chance with sellers offering replacements or substitutes.

It is important to note that even the genuine Honeywell filters are made mostly of paper. Knock-offs and substitutes can vary in quality, with some arriving unglued or having thinner or fewer pleats, indicating weaker quality control. While some of these alternatives may work adequately, it is up to the consumer to decide what matters most to them.

When comparing knock-offs or substitutes to the original Honeywell filters, several factors should be considered. The genuine Honeywell filters are made with a moisture-resistant frame, ensuring sturdiness even in high humidity. They also feature rust-resistant galvanized wire on the downstream side, keeping the filter media in place against the airflow. Additionally, built-in support fingers hold the pleats evenly spaced and in place, allowing for maximum dust retention.

It is advisable to shop around and compare prices before making a purchase. It is worth noting that a year ago, this particular item was being sold at a 42% lower price than the current average.

A customer who replaced their old electrostatic filter elements with this Honeywell filter found it to work great so far. They did encounter a minor issue with their Honeywell unit, as it had an alignment pin on the bottom wall that needed to be removed before the new filter could fit. This pin was easily removed by unscrewing a small Phillips screw.

Updating their review after a year of use, the customer noticed that the filter had collected a significant amount of dirt from the air. They mentioned having two dogs and a persistent dust problem, but did not find the filter to be a game changer. However, they appreciated the switch from electrostatic filters to the paper filter, as it eliminated annoying zapping sounds.

I recently discovered the 2-inch depth air return grille filters and wanted to find one that offered better filtration without sacrificing airflow. After searching online and finding expensive options, I stumbled upon these filters on Amazon and was pleasantly surprised by the pricing.

The filter I purchased has been holding up well for the past few months, although I don't run the blower all the time. One thing that stood out to me was the variety of MERV levels available, allowing me to choose the level of filtration I desired. I initially opted for the MERV 10 filters and was thrilled to find them at an amazing price on Warehouse deals. However, moving forward, I think I will stick with the MERV 8 filters for a good balance between filtering and airflow.

These filters are of great quality and are able to trap a significant amount of dust and other particles. I am never going back to the cheap, thin filters I used to buy. These filters are definitely worth the money and provide a noticeable improvement in air quality.

In addition to the improved filtration, I also purchased a set of these filters with charcoal backing. I was unsure if our system would give a warning about a plugged filter, but to my relief, it didn't. I have actually noticed a decrease in the amount of dust in the air when sunlight shines in certain directions, as well as less dust settling around the house overall. The charcoal backing may also be helping with odors, although I can't say for certain. Furthermore, I have experienced less allergy symptoms and improved breathing since using these filters.

I was so impressed with these filters that I decided to stock up and purchased a few boxes to have on hand. This way, I can change them out as needed without worrying about availability. I am confident in the quality of this brand and would not hesitate to try their 1-inch filter offerings as well.

I am extremely impressed with the thickness of this air vent filter material. It exceeded my expectations and gives me confidence that it will effectively filter out allergens. The quantity provided is also generous, allowing me to cover all my vents and have some left over for future replacements.

I opted to place the filters inside the vents rather than on the outside. To ensure complete coverage, I cut extra material so that it overlapped the entire vent when I reinserted it into the duct. This eliminated the need for the included Velcro. Even my dad, who helped me install them, was so impressed that he bought some for his own house.

I have read some concerns about reduced airflow caused by these filters, but personally, I did not experience any issues. As long as you are not already complaining about a lack of airflow, these filters should not hinder it. They even proved to be highly effective in combating the cigarette smell from my neighbor's house. Installation was a breeze, and these filters served as a great alternative to buying an air purifier.

I cannot emphasize enough how much of a lifesaver these filters have been. I reside in a barn house where the shop and living quarters share a heating/cooling system. Unfortunately, this also meant an abundance of dust. These filters have truly transformed my living environment, and I now swear by them.

I absolutely adore these filters! By not having them pre-cut, you get more value for your money. The weight of the filters is just right, allowing for efficient filtering while still allowing air to pass through. They have made a significant difference in my life, especially since I have multiple allergies and live in an old house.

These filters have worked wonders in reducing dust and odors in the older house I am currently renovating and living in. They have truly been a lifesaver until I have the opportunity to replace the ductwork. The roll provided more than enough material, and I did not notice any significant reduction in airflow. Considering the affordable cost and the benefits of having somewhat cleaner air, I highly recommend this filter material.
