There are many options for air filters. These filters can be classified by their MERV rating or type. You can buy Pleated filters for your home, flat ones for your office, and washable filters for your car. Here is a quick overview of all the different types.

MERV ratings

MERV ratings are an important factor in choosing an air filter for your home or office. These ratings are determined by the American Society of Heating, Refrigeration, and Air-Conditioning Engineers. The COVID-19 guidelines for buildings recommend using 20x20x1 air filter merv 13. These filters trap particles more effectively than lower-rated filters.

Pleated

If you’re looking for a good standard home air filter, you’ll need to know which one to buy. Pleated air filters can be used in many applications. However, it is important that you know what you want before you make a purchase. A pleated filter is a good choice if you have allergies or are sensitive to airborne pollutants. These filters are affordable and easy to change.

Flat

Flat air filters can be used in air conditioners and home furnaces. They have a MERV rating of one to four. This means they can remove particles as small and as small as three microns. These filters are not air purifiers. Instead, they are used to remove allergens, dust, and other contaminants. They also allow for maximum airflow.

Washable

For keeping your air clean, washable filters are a great option. These filters are easy to clean, cost less to buy, and last a long time. Washable air filters have one major drawback: they need to change frequently. The main advantage is that they’re environmentally friendly and save you money. However, you will have to pay to replace them. This is not always possible. It’s worthwhile in the end.

Media

Air filters can use a variety of media. These media can be synthetic or natural. They have a porous structure and are permeable to liquids and gases. An air filter must have the right porosity, chemical resistance, and mechanical strength to withstand filtration temperatures. Some of the media used in air filters also have other characteristics that make them useful in other applications.
