Do Air Filters Make a Difference in Your Home?

In its most basic form, an air filter is designed to remove impurities such as dust, pet dander, and even bacteria from the air that flows through the system. Not only does this improve the air quality inside your home, but it also helps protect your HVAC system from damage. When it comes to the health and comfort of your family, friends, and other guests, it's a good idea to get the most efficient air filter you can afford. Filters not only allow people to breathe easier, they can also reduce odors and make your home a more pleasant place to live.

If you want to take air purification to the next level, consider adding an air purifier. One type that can be difficult to find in local stores is the whole house air filter. These are very different from the more common one-inch filters. You may have heard them referred to as whole-house air purifiers, which is a misnomer.

An air purifier is an addition to your HVAC system, not part of it. Although air filters do clean the air, they are part of your system and are not optional.

What Are the Benefits of Air Filters?

Air filters provide several benefits for homeowners. They help keep your HVAC system running smoothly by preventing dust and dirt from clogging up the system.

This helps extend the life of your HVAC system and keeps it running efficiently. Air filters also help improve indoor air quality by trapping allergens and other contaminants in the air. This can help reduce allergy symptoms and make your home a more pleasant place to live.

Types of Air Filters

When shopping for an air filter, you'll find that there are several types available. The most common type is the one-inch filter, which is designed to fit most standard HVAC systems.

These filters are relatively inexpensive and easy to find in stores or online. If you're looking for something more efficient, consider a pleated filter. These filters have more folds (or pleats) than one-inch filters, which increases their surface area and allows them to trap more particles in the air. Pleated filters typically have a higher MERV rating than one-inch filters, which means they are better at trapping particles in the air. Another option is a washable filter.

These filters are designed to be reused instead of thrown away after each use. This makes them an eco-friendly option and can save you money in the long run.

How Often Should You Change Your Air Filter?

You've probably heard how important it is to change your home's air filter regularly. The frequency with which you should change your filter depends on several factors such as whether you have pets in the home or if mold is a threat. Generally speaking, it's best to change your filter every three months or so.


Air filters are an important factor in keeping your home clean and keeping the air you breathe healthy. When shopping for an air filter, make sure that you get one that fits your HVAC system properly and has a high enough MERV rating for your needs. Finally, look for online retailers that offer discounts on recurring shipments of air filters.
