Indoor air quality is really important, but it’s not something we spend a lot of time thinking about. The good news is there are some really easy ways to improve the air inside your home, including choosing the right air filter for your HVAC system. But aren’t all air filters created equal? Nope! A basic filter guide might help.
Air filters are rated using a MERV scale, which stands for Minimum Efficiency Reporting Value. MERV measures the effectiveness of a filter, with a high rating (16 is the highest) being the most effective. A filter that rates high on the scale means improved health for you, cleaner air, and a more energy efficient HVAC system.
There are a number of different types of air filters available. Everything from fiberglass filters, which are not very effective, to high MERV rated high efficiency filters. On the other hand, high efficiency filters can remove up to 85% of particle pollutants from your air. This will not only reduce the amount of dust in your home, but it can have dramatic effects on how you feel. Cleaner air can reduce the chance for viruses, reduce respiratory irritation and inflammation, and reduce allergy symptoms.
Whether you choose a pleated air filter, which can trap about 45% of pollutants but is more economically priced, or a high efficiency or HEPA filter, which are more effective but a bit more costly, the best advice is to make sure you’re changing your filter regularly. Every 2-3 months your HVAC system should get a breath of fresh air with a new filter.
In order to get the most from your air filter, you need to choose one with a high MERV rating, one that fits your HVAC system, and it needs to be changed regularly. For more information on air filters and additional ways to improve your indoor air quality, contact the team at All City Heat and Air.
