An air filter is an essential HVAC part for efficiency and comfort—but it’s often forgotten.
Filtration is one of the best techniques to clean the air that flows through your home. It catches particles as air moves through HVAC ductwork.
There are several models of air purification systems you can install to improve the air in your home. A-Plus can suggest what’s best for you. And you can breathe comfortably knowing all our Expert work is supported by a 100% Satisfaction Guarantee for a year.*
Indoor air quality can impact your family’s health, especially if there’s someone in your family with allergies, asthma or other respiratory issues. Dust, pollen, pet dander and mold can trigger symptoms, as well as volatile organic compounds. VOCs are chemicals located in common household items such as cleaning products, furniture and flooring.
Today’s houses are more energy efficient than ever, but they are also more airtight. This means the air inside your home can be more polluted than outside—often two to five times more, according to the Environmental Protection Agency.
There are methods you can use to take charge of your home’s air quality:
There are a couple of indications that your home could benefit from a filtration system.

A whole-home air purification system can take care of pollution in your home’s air. In fact, it can also bring relief to the asthma and allergy sufferers in your household.
Studies have found controlling exposure to indoor allergens and tobacco smoke could stop 65 percent of asthma cases among elementary school-age children. And by controlling biological contaminants like dust mites, childhood asthma cases have also decreased by 55-60 percent.
The High Efficiency Particulate Air, or HEPA, filter, was designed to protect scientists from radiation as they worked on the atomic bomb during World War II. Today these filters are frequently used in hospitals and science labs, but you can even find one in a few homes.
HEPA filters are proven to take out 99.97 to 99.99% of particles sized 0.3 microns and bigger. This includes pollen, dirt and dust. A HEPA air cleaner with activated carbon filters can eliminate the particles from chemicals, odors and smoke.
These filters boast a MERV rating of 1721, depending on the brand. This rating shows how well a filter can pull out pollutants from the air.
Because of their high-efficiency filtration capabilities, HEPA filters are thick and can limit airflow. It’s important to check with A-Plus to confirm your heating and cooling system can work with one.
Media air cleaners are denser than your standard air filters. They’re often four to five times wider—or more. This barrier fits tightly against your HVAC equipment.
Because its filtration surface is usually around 10 inches, media filters are able to capture about 95 percent of particulates.
These filters last longer too, usually between three to six months.
There are a few electronic filtration systems you can install in your home.
An electrostatic filter utilizes magnetically charged components to attract particles. These washable filters are 97 percent effective at extracting microscopic particles from your home’s air. In addition, they’re also 30 times more effective than ordinary filters.
An electronic air cleaner applies a high-voltage magnetic charge to catch particles.
Some models can remove the majority of indoor air pollutants—particles, germs, bacteria, chemical odors and vapors—by up to 99.9 percent. It can even decrease ozone, a known lung irritant, created elsewhere in your home.
Air inside your home can be more polluted than the air outside—often two to five times more, according to the Environmental Protection Agency.
