Air filters play a significant role in keeping particulate matter, including dust, debris, viruses, and bacteria, out of your home’s air. This keeps you from contracting respiratory diseases and allergies while prolonging the life of your HVAC system. Read on for four tips for choosing suitable air filters for your home.

1. Determine the right size

Air filters come in different sizes and shapes. Ensure that you choose the right filter size and shape to prevent dirt, dust, pet danders, and debris from slipping into the air conditioner, as this could compromise the indoor air quality. To determine the correct filter size, you could consider carrying the existing filter with you when buying a new one. Other ways to determine the correct filter size include;

• Checking the manufacturer’s instructions
• Measuring the opening or filter
• Referring to printed dimensions

2. Figure out the correct MERV rating

MERV ratings determine the efficiency of your filter unit. The Minimum Efficiency Reporting Value (MERV) ratings dictate the size of particulates a filter can keep out of your house’s airflow, how long the unit can last and how well air flows inside the HVAC. The higher the ratings, the smaller the contaminants the air filter can trap. With that being said, do not go for an air filter with the highest MERV rating, as this could increase your home’s energy consumption. An ideal rating should be between MERV 8 and 10 to help you balance energy efficiency, airflow, and air purification.

3. Consider the filter’s maintenance

Continued use of an air filter causes particulate matter to accumulate in the unit. You have to clean or replace the filters every three months to prevent an HVAC malfunction and increased energy bills. If you are working on a tight budget and do not want to purchase a new filter once the existing one becomes clogged, consider choosing a reusable or washable unit. Be sure to follow the manufacturer’s instructions about the proper cleaning procedure.

4. Consider the material

Your filter’s material plays a crucial role in the performance of your air conditioner and the type of particulate matter it captures. The different air filter materials include;

a) Electrostatic Polypropylene filters

Electrostatic filters use a combination of triboelectric charge and airflow to remove air pollutants. These filters are perfect for removing small-sized pollutants such as dust. However, this filter material is expensive to purchase and maintain and could strain your AC as it reduces airflow.

b) Pleated air filters

Pleated air filters are the most common filters in most homes as they trap particulate matter as small as 0.3 microns, such as bacteria and viruses. They also have pleats that increase the filter’s surface area for maximum air purification,

c) Fiberglass air filters

This is the cheapest air filter material, so it is perfect under a tight budget. However, fiberglass filters only trap large particulates, which means that it may not be ideal when looking to improve your indoor air quality.

d) Carbon filters

Carbon air filters prevent odor and fume build-up in recirculated air through adsorption. However, carbon filters do not trap smaller particles such as bacteria and dust from the air.

Endnote

Air filters are crucial in improving indoor air quality. Keep the above tips in mind to help you select the right air filter for a healthy home environment.
