An air filter is a device that eliminates pollutants from the air. These items significantly affect the HVAC system’s performance and should be replaced often for the best results. However, most homeowners overlook the importance until they break down.
These items are available in different types, and you are advised to research them properly before buying. However, the filter-buying process is complex, as different homes require different filtration levels.
This unit should be replaced often, as faulty filters can facilitate the spread of pollutants. Below we discuss how to choose the best air filter.
- Filter Model and Size
The first step in buying an air filter is knowing its model and size. This information is essential, as it informs you whether the filter fits your home. You are advised to know your filter size to avoid losing money by buying the wrong size. Most filters have their size indicated on the side, making it easy for buyers. Kindly choose a filter with a MERV 13 rating for the best results.
However, you are advised to carry a measuring tape to get an accurate measurement. Homeowners are also advised to know the filter’s model since it lets them quickly find the one they want. There are also aftermarket filters that fit specific models.
- Aftermarket or Original
Particular brands manufacture some air filters to meet the brand’s model; they are known as original filters. On the other hand, aftermarket filters are manufactured by other organizations to fit different brands.
Aftermarket filters are designed precisely as original filters but are available at a cheaper rate.
- Home Air Quality
Home air quality is another top consideration when buying an air filter. Homes with poor air quality should go for a better quality air filter. The most common causes of poor indoor air quality include;
- Pets
- Smoking
- Poor ventilation
- Outdoor environment.
Some premises are designed with tight insulation that enhances the amount of indoor pollution. Lower outdoor ventilation makes the air pollutants accumulate indoors, putting more pressure on your air system.
Premises with pets or smokers also have many indoor air pollutants, meaning they need a high-quality air filter.
- Particular Breathing Needs
Some individuals need top-notch air filters because they have breathing issues. These are mainly people with allergies, bronchitis, and asthma. Also, children with renowned health conditions would gain a lot from a high-quality air filter.
- Filter Type
The filter type is another significant consideration when buying one. As stated above, filters are available in different types, and the most common include;
- Electronic filters
- HEPA filters
- Pre-filters
- Electrostatic filters.
Asthmatic people should opt for HEPA or electrostatic filters since they are explicitly designed to eliminate microscopic elements like tobacco smoke. Electronic filters also trap many microscopic elements but are not common.
Carbon filters are ideal for people who struggle with indoor odors.
