The MERV rating is the standard used to determine the filtration ability of an air filter. The lower levels provide decent filtration while the higher levels provide greater filtration. MERV ratings are useful in comparing filters because different levels can capture different types. The 20x20x1 air filter with the highest MERV rating of 16 will capture the smallest particulates.

Pleated air filters

If you’re trying to improve the indoor air quality of your home, pleated air filters are the way to go. Pleated air filters have a larger surface area to trap mold, dust, and other allergens. This is important as flat filters let more particulates through. The longer the pleated filter lasts, the more material it has to catch contaminants. Pleated air filters are not only better for indoor air quality, but they also save you energy.

While flat air filters are not effective at improving the quality of your home’s air, pleated air filters will improve your indoor air and help you breathe easier. Pleated air filters are also more durable, making them the best choice to improve your home’s HVAC system. Plus, you can get them at discount prices from Discount Filters, which offers free shipping on all filters. A pleated air filter will also protect your home’s HVAC system from damage.

Media filters

A high-efficiency replacement filter media is usually reusable and does not require frequent replacement like furnace filters. High-MERV filtration means that it is highly effective at trapping airborne particles and odors, but it doesn’t reduce static pressure or airflow. It can also last six to twelve months.

A media filter is installed in an HVAC system’s return line. It prevents harmful particles from entering your home or business. It does not restrict airflow in the ducts and also removes smaller particles. It is also more durable and can be easily changed two to four times per year. These filters come in a variety of sizes.

Washable filters

Washable filters trap dust particles with static electricity. Washable filters are great for basic filtration, as they can trap larger particles with static electricity. They should be changed and cleaned regularly to maintain their efficacy. But what are the pros and cons of washable air filters?

The first thing to know about washable air filters is that they get dirty over time. This is normal. You should use a mild household cleaner to clean washable air filters. Once that’s done, it’s time for them to be dried. However, you should be careful to avoid getting water or other liquids on the filter. It’s important to clean them regularly and keep them as clean as possible to avoid bacterial growth.

MERV ratings

MERV ratings are a way to determine how efficient an air filter is at capturing dust particles. The higher the MERV rating, the better the filter. Air filters are tested for their ability capture particles in the E1, E2, E3 range. The higher the rating of the MERV, the greater the air filter’s filtration capacity. This information helps you decide which air filter is best for your home.

When choosing an air filter for your home, MERV ratings are important. A higher rating does not necessarily mean a more efficient filter. A higher MERV rating might not be necessary for your specific needs. The American Society of Heating, Refrigerating, and Air Conditioning Engineers developed the MERV scale in 1987. It emphasizes the effectiveness of air filters in removing dust particles and other pollutants. MERV ratings allow you to compare the performance of different models and brands.
