You should use a 20x20x1 air filter if you are concerned about airborne particles. There are different types of air filters, including HEPA, Pleated, Electrostatic, and Fiberglass filters. A good filter will remove a greater number of particles than a poor filter. There are many filters available, so it is important to consider your needs when choosing the right filter. 
Pleated air filters
Pleated air filters can be a great way of protecting your home from many pollutants. Because the filter media is made of pleats, it traps more particles and allergens than other types of air filters. This filter is made from synthetic fibers and comes in a variety sizes, ranging from one inch to six feet. Most of these filters can be disposed of once they are used, so they are easy to replace.
HEPA air filters
A HEPA filter is a type filtration system that captures microscopic particle. HEPA filters can trap particles larger than 0.3mm. They try to pass through the interception section, but they are too large to pass through the fibers. They are then trapped inside the filter, and this slows down or prevents them from traveling through the filter at all. This process is known as impaction. This is the best way to protect your family and yourself against airborne particles that can cause asthma and other respiratory diseases. Short on funds but really want to shop online?

Electrostatic filters
The static force of electricity is used to trap tiny particles in electrostatic air filters. These filters have two plates. One is positive-charged and the other is negative-charged. The positive charge plate is where particles pass through, while the negative charge plate is where they stick to. This allows dust and other airborne particles to be captured. Although these filters are not perfect they are an excellent choice for allergy sufferers.
Fiberglass filters
Fiberglass filters for air filters come in either one-inch or two-inch sizes. These filters are made from continuous glass fibers and look similar to pleated filters. These filters are very effective in removing invisible particles from the air and are inexpensive to buy. However, they must be replaced frequently and may not be suitable for certain types of HVAC systems. It is essential to find a compatible filter of high quality for your system.
Washable filters
