When choosing an air filter, you will frequently see MERV and MPR ratings which measure air quality. The Minimum Efficiency Reporting Value (MERV) is based on the efficiency of your air filter in comparison to other models. The Microparticle Performance Rating (MPR) was created by and is only used by 3M, so only filters under the 3M / Filtrete brand contain an MPR rating.
Air filters can be disposable or washable, so choosing between the two depends on your own needs and lifestyle. If you suffer from allergies and need to frequently replace filters, you might consider using a washable or reusable filter.
These also hold an economical advantage since there is less to buy. The disposable ones are fantastic options for individuals who do not want to bother with the washing required for reusable filters.
Another common difference is whether they are pleated or not. Pleated filters are usually made from a synthetic wire material that allows the filtering of microscopic particles. Non-pleated air filters are most effective for large particles, such as lint, dust, and even insects.
Since you know the size of the air filters you need, let’s get right into the reviews! In case you want to go through the basics of air filters, we recommend starting with our article on the best air filters for airflow.

The Best 20x20x1 Air Filters Reviews
1. Filtrete Micro Allergen Defense 70071247152 – Air Conditioner Filter 20x20x1
Features
- Rating: MERV 11 and 1000 MPR
- Color: White
- Type: Electrostatic
- Pleated: Yes
- Recommended Duration: Up to 3 months
The well-known Filtrete brand, made by 3M Corporation, has earned a reputation in the filtration industry. This Micro Allergen Defense model is more than just an ordinary air conditioner filter. With an MPR rating of 1100 (equivalent to a MERV 11 rating), this provides a high degree of filtration to get impurities out of your air. Since MERV ratings range from 1 to 16, this air filter is a great choice when considering having desirable air quality.
Created using a washable and reusable material, this is a fantastic option for you if buying air filters frequently is unappealing. This reusability factor also adds an environmentally friendly element since you don’t have to constantly purchase and throw away new air filters. Eliminating the waste that disposable filters cause makes this a “green” alternative.
These filters are electrostatically-enhanced and have been created with several layers. They are commonly referred to as electrostatic since the friction between the air and the filter causes the air molecules to become positively charged. This static creates a charge that essentially sucks in all of the unwanted air parts, leaving you with a higher quality of air to breathe in each day.
Pros
- Reusable
- Surpasses fiberglass designs
- Large and small particles
Cons
- Frequent washing necessary
2. Flanders PrecisionAire 10155.01202 EZ Flow – Washable Air Filter 20x20x1
Features
- Rating: MERV 4
- Color: White
- Type: Disposable
- Pleated: No
- Recommended Duration: Up to 30 days
The Flanders PrecisionAire has both an economic and environmental value. With a Flat Panel EZ Flow design, this filter protects your HVAC unit with a one-piece design which is easier to install than some other models. The metal retainer is surrounded by a chipboard frame, allowing for a strong design built to last longer.
Manufactured using a spun-glass filter, PrecisionAire offers a low-resistance option for reducing pesky air particles and bringing in waves of fresh air. This cycle of airflow is essential for improving the quality of air that you breathe daily.
Being disposable, this filter is a no-fuss product that is easy to throw away. This is important to remember when you are due for a filter change but do not have the time or patience to wash one of the reusable alternatives. You do indeed want to replace your filters regularly since older ones are going to remove fewer germs and bacteria from the air.
Pros
- Disposable
- Durable design
- Low-resistance
Cons
- Non-reusable
- Higher replacement costs
3. Filtrete Healthy Living Ultra Allergen UR02-6PK-1E – 3M Air Filter 20x20x1
Features
- Rating: MERV 12 and 1500 MPR
- Color: White
- Type: Electrostatic
- Pleated: Yes
- Recommended Duration: Up to 3 months
Known for its superior filtration, the Filtrete brand does a fantastic job of grabbing onto the usual suspects in terms of allergens such as dust mite debris and pet dander. It simultaneously lessens the amount of dust commonly found in homes and businesses, making this ideal for people with dust allergens or those with asthma.
While great at gathering larger items like dust and lint, the Healthy Living Ultra Allergen model is particularly adept at attracting and retaining microscopic material such as germs from coughing and sneezing. Not too many other air filters can offer that level of filtration to improve air quality.
This air filter uses 3-in-1 technology by sucking in undesirable air particles, trapping them, and then providing you back with fresh air in return. With this technology, you are less likely to experience poor indoor air quality and higher energy costs.
Pros
- Very high MERV rating
- Reusable
- Microscopic particle attraction
Cons
- Frequent washing necessary
4. True Blue 120201 – True Blue Air Filter 20x20x1
Features
- Rating: MERV 2
- Color: Blue
- Type: Fiberglass
- Pleated: No
- Recommended Duration: Up to 30 days
As a more affordable air filter, the True Blue Air Filter allows you to improve your air quality without breaking the bank. With the ability to hold a high amount of dust, this is not an inefficient filter by any means. Being disposable allows you to toss this filter after it has collected all of that dust and debris.
The surface of the True Blue filter is covered with an adhesive gel that creates a comparably thicker barrier to larger materials. This barrier is what allows it to hold a high amount of dust due to better depth-loading. In addition to providing overall better air quality, you should consider this an affordable option, particularly If you have a problem with dust.
The dust is only one factor in a dirty air filter which is an essential part of your HVAC unit. If left unchanged, an old or unclean filter will certainly slow down the airflow and will waste energy by forcing your system to work harder. So, you can save money on energy costs as well as your time and aggravation by selecting this disposable filter.
Pros
- Disposable
- Depth-loading
- Low-resistance
Cons
- Short-lived duration
- Higher replacement costs
Conclusion
All in all, if you want your AC to work properly, filter maintenance is the way to go! And, what’s better than getting the best 20x20x1 air filter for the unit you have. Just make sure to double-check the ratings and the materials, so you know whether or not it fits your habits and lifestyle.
