Things to consider when choosing a filter:

Filter model and size

Before you start to pick a specific type of filter, you need know both the filter size that fits your air system and the model. It is very vital to know the size of your filter because you want your filter to fit, also, you do not want to lose money buying the wrong filter size. Most filters already have the size printed on the side, but sometimes that is a rounded size, and sometimes filters are undercut up to half an inch of the real size. To be certain that you have the right measurement, use measuring tape and measure the height, depth, and width of the filter.

Home air standard

One thing to consider when picking a filter is your homes air standard. If your home has bad air standard, then you might need to consider a higher standard air filter. Some general factors that lead to lower indoor air standard include:

Tight insulation

Bad ventilation

Smoking

Pets 

Outdoor atmosphere

Some homes are built strongly insulated, which actually rises the amount of inside air pollution. Bad ventilation of open-air leads to the accumulation of inside air pollutants inside, which means more force on your air system as it pulls in air with more particulates.

Types of filter

Why type of filter do I need? This is very vital question when picking a filter. There are many different kinds of air filters on the market, and most are designed with specific needs in mind. Here are most general types of filters:

HEPA filters

Carbon filters

Electrostatic fitters

Pre filters

Electronic filters

If you suffer from breathing issues like allergies or asthma, then you likely need an electrostatic filter or a HEPA filter. These filters are mainly designed to remove microscopic allergens like mold spores, dust mite debris, tobacco smoke, pollen grains, pet dander, and bacteria. Electronic filters are also trap a big range of microscopic particulates, but they are not the most general, and some of them produce ozone.

Filter cost and replacement

When picking a filter, definitely there are financial considerations as well. How much does a top standard filter cost? The cost truly depends on which filter you pick, whether it is a real or an aftermarket, and the size of the filter. The higher the rating and the bigger the size of the filter, the higher the price is going to be. Also, not all filters come in normal sizes; you may be capable to find the right measure in the type of air filter you want and you may have to have 1 custom mode, in which case the price is generally a bit higher.
