What to Consider When Choosing the Best Air Filter Subscription

While it’s easy to assume that air filter subscriptions offer similar levels of service, a number of factors affect their functionality and appropriateness for different households. Keep reading to learn about several of the most important features to consider when choosing the best air filter subscription.

MERV Rating

MERV stands for “minimum efficiency reporting value.” An air filter’s MERV rating represents its efficiency. MERV ratings range from 1 to 20: A higher rating indicates a higher level of filtration, and filters with higher MERV ratings generally cost more per filter.

Number of Filters

Every household requires a different number of filters for its HVAC system and furnace. To establish how many filters are necessary for a particular system, first locate the existing filters, which should be inside the home’s return vents. These vents are often next to the furnace or HVAC handler. Each vent generally has its own filter.

Be sure to check the dimensions of each filter in the system because they may differ. Most subscription services allow subscribers to order multiple filters at once, and many also include an option to order several filters of different sizes.

Filter Dimensions and Compatibility

Since air filters come in a wide variety of sizes, first establish which size the system requires. Some of the most common sizes are 16 by 20 inches, 20 by 25 inches, and 16 by 25 inches. Filters also vary in thickness, and while a thicker filter is generally associated with higher performance, each furnace or HVAC system’s instructions stipulate the maximum thickness it can handle. The exact size should appear on the edge of the filter that came with the system.

Check the owner’s manual for each specific system to compare prices for a specific filter size before committing to a subscription service. It’s essential to use only filters recommended by the manufacturer to reduce the risk of voiding the system’s warranty.

Shipping Frequency

Shipping frequency depends on how often an air filter must be changed, which depends on a variety of factors.

Fiberglass filters, for example, should be changed every 30 days, while most pleated filters last 60 to 90 days. While households with allergy sufferers or pets should change their filters more frequently, HVAC filters in vacation homes can be changed less often.

Many air filter subscription services offer flexibility in delivery intervals. The best air filter subscription services allow customers to choose delivery frequency based on their needs.


While you now know more about choosing the best air filter subscription service, you may still need more information about ensuring optimal air quality in your home. Read on to find some answers to some of the most frequently asked questions about home air quality and air filters.

Q. Are air filter subscription services worth it?

Convenience is the primary advantage of an air filter subscription service. Rather than calculating when filters must be replaced throughout the year and heading to the hardware or home improvement store, subscribers can have their filters delivered directly to their door—and receive a gentle reminder when it’s time to change them.

Q. How much do air filter subscriptions cost?

The price of air filter subscriptions varies based on the type of filters chosen and the frequency with which they are delivered. Some services offer discount air filters with bulk purchases. When using a subscription service, the price per filter typically starts at about $15.

Q. What does “MERV” mean, and how does it affect the price per filter?

MERV stands for “minimum efficiency reporting value.” An air filter’s MERV rating represents its efficiency. MERV ratings range from 1 to 20: A higher rating indicates a higher level of filtration. Filters with higher MERV ratings generally cost more per filter.

Q. Which MERV rating is best for home use?

While HEPA filters—which have a MERV rating between 16 and 20—are considered the gold standard in commercial and medical settings, disposable pleated filters with MERV ratings of 8 to 12 are sufficient for home use.

Q. Should I change my air filter monthly?

While fiberglass air filters should be changed monthly, pleated filters can be changed less frequently.

Q. What is an HVAC filter program?

An air filter subscription plan also may be referred to as an “HVAC filter program.
