Air Filters (646 items found)

Indoor air can quickly become polluted with dust, allergens, pet dander, bacteria and more. By installing a clean air filter in your central heating or cooling system, you can better clear these pollutants from the air for a more comfortable experience that greatly improves your home’s air quality.

Are Air Filters, Furnace Filters and Air Conditioner Filters Different?

Some commonly used names you’ll encounter for an HVAC filter include air conditioner air filter, furnace filter and AC filter. Although they sound different, they typically refer to the same thing. While you should be able to use any filter that fits interchangeably in your furnace, air conditioner, or other home filtration device, always consult the manufacturer’s instructions for the best fit.

Air Filter MERV Ratings Explained

MERV, or Minimum Efficiency Reporting Value, is a standardized measurement for air filter efficiency. The scale ranges from 1 to 20: the higher the number, the finer the filter, and the more efficient it is at removing pollutants. 

How Often Should You Change Your Air Filter?

For the best performance, try to change your home air filter every 90 days. Leaving a filter for longer can result in your heating system having to work harder to deliver air, while the air filter is less efficient at removing pollutants and other irritants.

At Ace, we offer plenty of air filter replacements in bulk, making it quick and easy to make changes when they’re needed.

How to Choose the Right Air Filter

With so many options for different air filters for home use, it can be challenging to know which one is the right fit for your needs. Here are a few things to know as you shop around.

Choose Your MERV Rating

When choosing your new furnace or air conditioner filter, begin by assessing your home's air filtration needs. If you're looking for a simple and affordable filter that does a good job of removing general pollutants, many people start with a MERV rating of 4.

However, if someone in your home has allergies or asthma, you may want a finer filter that can remove smaller allergen particles. MERV ratings of 8 are a popular choice for removing allergens, but filters with a rating as high as 15 are common for in-home use. Refer to our handy guide above for a more detailed look at which air filter MERV rating is right for your needs.

Panel vs. Pleated Air Filter

You will have to decide between pleated and panel air filters. Flat-panel filters are inexpensive and are solid options for filtering out pollen, pet dander and dust. However, they are not as durable as pleated filters and often have lower MERV ratings. You can find a pleated HVAC air filter with a higher MERV rating, but it will also be more expensive. However, pleated air filters typically last longer. 

Choose an Appropriate Filter Size

Before you shop for a new home air filter, remember to check the size of your furnace or AC unit. If you know your required length and width, simply filter through the options above to narrow down your choices.

Air Purifier Filters

Air purifier filters are a type of air filter, but not all air filters are meant for air purifiers. Air purifier filters are specifically designed for air purifiers. They are often more sophisticated and can capture a wider range of airborne particles, including dust, allergens, smoke and even some germs.

Humidifier Filters

A humidifier combats dry air by turning water vapor into the air, easing congestion and coughs. Humidifier filters rap dust and minerals in the water before they're released, improving air quality and protecting the humidifier itself.
