MERV Ratings

The first step to understanding everything there is to know about air filters is knowing how they are rated. MERV ratings range between 1 and 20 and account for how effective an air filter is at doing what it is supposed to do: filter the air. The higher the MERV rating on the air filter, the better it is at catching air pollutants. Simple, right?

An important fact to note is that as the rating increases, so will the price. More importantly, a higher MERV rating is not always the best option. The thicker the air filter is, the more air pollutants it will catch. However, it will also restrict air flow at a greater rate. Low airflow can present its own problems, which is why you should always look for the perfect match of air filtration and flow when shopping for filters.

Natural Air Filters

What a lot of homeowners don’t know is that there are all-natural ways that you can filter the air in your home. Various indoor plants can filter out air pollutants such as benzene, ammonia, and formaldehyde. These plants benefit your overall respiratory health and save you from issues like eye irritation, dizziness, and a ton of other health issues!


Fiberglass filters are your standard, everyday air filters. They do an overall average job, removing 10% of the air pollutants in the home and do little to restrict air flow. That said, their MERV rating is usually between 1 and 4, which can leave customers desiring more, especially during allergy season.

If you don’t suffer from seasonal allergies, don’t own a pet, and live in an area that doesn’t have an abundant plant life, then this is the option for you. The best part is that they are very cost-effective and should never cost you more than $5!


Polyester filters are a slight upgrade from their fiberglass counterparts. They have a higher MERV rating, between 8-13, meaning they catch more air pollutants and restrict air flow at a greater rate, but not by an enormous amount. You can expect to pay more for them, but if you’re in the right situation for a polyester filter, it can be well worth the cost!

A polyester filter can remove about 40% of the air pollutants in your home and alleviate the costs of your monthly energy bill. They’re the perfect choice for allergy season and allergy sufferers.


Washable air filters are the perfect choice for those looking to make a one-time buy. They don’t have the best MERV rating, as it is typically around 1-5, but they are by far the most cost-efficient. While you may pay $5 to $15 multiple times a year for disposable air filters, you can pay $20 one time, and reuse this air filter for five to ten years.

You must stay on top of your air filter’s maintenance at all times. Make sure you clean it often, which can be done with a hose, and dry it to prevent mold. Other than that, these air filters are a good choice for budget-conscious HVAC owners.


High-efficiency filters are the best in the industry at removing pollutants from the air. That said, they’re so good at what they do, they’re almost unnecessary for homeowners. High-efficiency air filters remove about 85% of the pollutants in the air, but also restrict air flow at a higher rate than other filters.

These filters are so good at what they do, they’re typically only used in hospitals or business settings where clean air is an absolute necessity. Unless you have pre-existing health conditions where a doctor has told you that clean air is a top priority, high-efficiency is probably not for you.
