How To Choose the Best Air Filter Subscription Delivery Service

There are a variety of factors to consider when choosing the best air filter subscription service, such as cost, shipping frequency, and customer service.


Costs appear pretty standard from subscription service to subscription service, so it will be easy to tell if one company you’re looking at is much less budget-friendly. On average, MERV 8 filters cost $12, MERV 11 filters cost $16, and MERV 13 filters cost $20.

Quantity of Filters

Before placing an order with an air filter subscription delivery service, determine how many filters you have in your home. Some companies allow you to order as few as five filters, while others allow you to select up to 12 filters at a time.

Filter Dimensions

In addition to determining how many air filters you need, check each filter’s dimensions and make sure you’re ordering the correct sizes when placing an order. Additionally, check with your subscription service and ensure it has all of the filter sizes you need.

Shipping Frequency

If you own pets, have asthma or allergies, or experience poor air quality where you live, you may need to replace your filters more frequently. Check with your air filter subscription delivery service to ensure it can send replacement filters every one, two, or three months.

Customer Service

If you run into any issues with your air filter delivery, you’ll want to work with a trustworthy company that’s easy to reach over the phone or via email. It’s also beneficial to work with a company that has an easy subscription management process.

Are Air Filter Subscription Delivery Services Worth It?

Because it can be difficult to remember exactly when to change your air filters, subscribing to a service can be worth the cost. Opting in to one of these services can prevent you from setting calendar alerts and taking trips to the hardware store to purchase filter replacements.

Not to mention, the air that’s recycled through your old filters can be bad for your health and your HVAC system, leading to high energy bills and potentially expensive repairs. Subscribing to an air filter delivery service takes away all of the guesswork when it comes to changing your filters and gives you peace of mind that your system will continue to run efficiently.

Frequently Asked Questions

What MERV filter is best for home use?

MERV, also known as Minimum Efficiency Reporting Value, is the rating that demonstrates how effective an air filter is at filtering out particles of different sizes. The higher the MERV value, the more effective the filter is. People who have pets or who experience asthma will need an air filter with a higher MERV.

How do I choose an air filter?

The first step of choosing an air filter is determining the size you need. Before purchasing new filters, ensure the air filters you order match the same-sized filters that are currently in your system. If you have respiratory issues or own several pets, you may want to consider a true HEPA filter with a higher MERV value, as this type of filter is better at filtering out dust, debris, and allergens. In terms of manufacturing, American-made air filters appear to be popular with air filter subscription delivery services.

How often should I change my air filters?

The frequency with which you change your air filters will depend on a variety of factors, such as the number of pets you have, where you live, and whether you have asthma, allergies, or other respiratory issues. In general, you should change your air filters every three months. However, if you have multiple pets or suffer from allergies, consider changing your filters every one to two months.

What happens if I don’t change my air filters?

If you don’t change your air filters, you’ll be recycling allergens back into the air that could trigger asthma attacks or allergy issues. Not replacing your air filters can also cause your HVAC system to run less efficiently, which will increase your monthly electricity bill and potentially lead to costly repairs or a complete system breakdown.
