Some are thicker than others, making it more effective at filtering the air in your home and eliminating pollutants.

Some filters are better for homes, some for businesses. Depending on your specific needs, a regular air filter might be the best option. In this blog, we will discuss all the major types of filters, what makes them unique, and where they are best suited for use.

MERV Ratings

Before you consider purchasing a filter, it’s important to know that a MERV rating is issued to describe how efficient an air filter is. The higher the rating is, the more particles and pollutants it takes out of the air you are breathing. Ratings for businesses and homes can range between 1 and 16, so pay attention to them next time you’re looking for a new filter.

Fiberglass Filters

Fiberglass filters are the most common kind you will find and can be regarded as the industry standard; they get the job done, and they’re inexpensive. They’re not the most effective at filtering the air in your home, but they get the job done. Fiberglass filters are made up of a thin sheet of fiberglass that catches particles as they fly through your air ducts, and they are a vital part of a clean home.

They typically sell for less than $5 and remove about 10 percent of the pollutants in your home.

Polyester – Pleated Filters

A step above fiberglass, the polyester filters are a thicker filter and are better at trapping dust and pollutants inside your home. They can typically remove up to 45 percent of the pollutants in the air you are breathing, but restrict air flow a little more. They’re slightly more expensive than their fiberglass counterparts, but the cost is well worth the added benefits. Their MERV rating usually lies between 8 and 13, and should be the first choice for homeowners who suffer from allergies or live among contaminants!


Washable filters are the perfect choice for those looking to save money long term and have a positive impact on the environment. You purchase one for about $25, and it will last you five years. That doesn’t mean you can just set it and forget it; rather you must be vigilant in cleaning it once every month or two. As washable filters catch more particles in your airways, the filter gets thicker from particle buildup, so there is somewhat of a snowball effect. That said, you still ought to wash it regularly to make sure your air flow goes unimpeded.


Highly efficient HVAC filters can remove up to 85 percent of the pollutants in your home’s air. They typically cost anywhere around $25, but they are the most efficient filters in the industry with a MERV rating of up to 16. They are made out of thin, pleated paper that will filter just about anything out of your home. That said these are your heavy duty filters and restrict air flow much more than the fiberglass or polyester options, so they are only necessary if your home is constantly filled with pollutants and particles or you require a cleaner environment.
