The air quality in a home is important for its inhabitants to continue to live a healthy life. Homeowners should strive for a cleaner and better atmosphere inside their residences. One step of doing this is securing the right air filters for you and your family. The appropriate choice would give provide air you could be confident to breathe in.

Air filters vary in kind and in its effectivity. Given the number of options on the market, you should know the factors when choosing a filter.

MERV Rating

This is a classification system made by ASHRAE. The purpose of the MERV rating is to classify the different types of filters. It's rating depends on how effective it is in trapping different particles.

These ratings range from 1 to 20, with 14 to 20 being in medical settings. Categories 1 to 4 are the most common, yet the most ineffective. MERV 8 to 13, are the best choices for homes.

If you want a better home environment, you should refer to MERV Ratings when deciding what air filter to use. Each number implies the filters capability to strain out certain particles. Familiarize with each rating and their capabilities. For example, the presence of pets or animals would change the MERV rating you would need. You would have to go for air filters with a MERV rating of 5 or higher to keep out their dander.  

Washable Vs. Disposable

There is a choice of washable and disposable air filters now. People often wonder which one is better. The truth is it is actually subjective, depending on a person’s preference.

Washables are great for money on the long-term. They cost more than disposable ones when you buy them. But, they save you money over time since you can use them for years. You only need to wash them when there is an excess build-up of particles and debris. Another upside of washables is that they are great for the environment. You won’t have to throw out your filter every few months.

Disposables are cheaper but because you have to buy new ones every time you change them, it will cost you more. The downside of disposables though, is that their MERV ratings only span up to 4. If you want one at a higher rating then washables are your only choice.

Right HVAC System

Unfortunately, you can’t pick out a filter from the shelf with a MERV rating of 20 and install it into your HVAC system. The higher the classification of a filter, the more it also restricts airflow. If you use filters with a high MERV rating, you need to have a system that is powerful enough to handle this.
