In the heating and cooling industry, there are the standards for the manufacture of air filters. The density of filter material is set from MV1 to MV20 (or MERV). The higher the number is, the denser the filter material is. For the general user, I recommend using an MV7 or near MV7 air filter (relative to 3M air filter, about 700 MPR). In addition, the thicknesses of air filters are usually 1, 2, 4 or 5 inches. As the air filter becomes thicker, if you keep the size and ventilation ducts of the machines unchanged, you can choose a denser filter material. Because of the thicker size, the ventilating area is increased and the amount of air flow to maintain the original flow is unchanged.
On the contrary, if we use a thinner air filter, we must choose a less dense air filter. If we want to reduce the original thickness of the air filter, we also have to use one with a lower density. It would shorten the replacement time interval if we have been using a thin air filter but would like to use a denser one (for example, in order to prevent allergies). Another point to note is that we can only put in one air filter at a time. Do not put two or more to meet the thickness you want. The average family needs to replace air filters every three to six months. It should never get to the point where the air filter is fully covered by dust.
If there is a house being built or construction near your house and the amount of dust in the air has increased, it is necessary to replace the air filter more often than usual.  If you are decorating either your house or your basement with dry walls, it is recommended to use plastic paper to isolate the dust. Seal the heating and cooling air intake in your work area with tape temporarily, and do a daily inspection or timely replacement of air filter. Having one air filter is enough for an entire heating and cooling system. Air filters do not need to be placed at the inlet and outlet. If this is done, it will only cause more trouble.
Air filters are the cheapest parts in a heating and cooling system. Regular inspection and replacement will not only clean the air inside the house while extending the life of the machine, they will also save money for you. Please do not underestimate the role of air filter maintenance!

Additional Information

The air filter in heating and cooling systems resists dust in the air, not only making indoor air clean but also preventing dust from entering the inside of the machine, especially in the evaporator coil (which is the main part of cooling system). If the dust accumulates inside the evaporator coil, the cooling system’s efficiency is reduced. The compressor withdraws the liquid refrigerant, which is incompletely absorbing the heat and is not fully vaporized.
Over a long period of time, it is easy to damage the machine. With the low efficiency of the cooling system, it uses more electricity to lower the temperature, so the electricity bill gets more expensive. In the winter, the hot air made by electric or gas heaters goes through the gap of the evaporator coil. If these gaps are clogged with dust and restrict the air circulation, a mechanical failure will happen. So, when we make the choice of an air filter, what is the best choice? Is filter material better when it is denser.
When selecting the air filter, we not only need to consider resistance to dust, but also think of the amount of air flow through the heater exchanger and cooling evaporator coil, both of which should be mutually balanced. Usually when we make the choice of an air filter, everyone thinks that the denser filter material is better while ignoring the necessary amount of air flow that should be in a normal heating and cooling system. In actuality, the air filter with denser material holds more dust and the air resistance is also larger. Because of the dirty air filter, the amount of air flow will be reduced. There is not enough air flow, which causes a problem of heating and cooling systems. If the lack of air flow conditions exists for a long time, the life of the compressor will be greatly shortened.
