How Often Should HVAC Filters Be Changed?

It is very easy to get tips for filter replacement and other related issues with the HVAC systems, but few people pay attention to an essential question related to it. Do you know how often you should replace the HVAC filters and howactually to change them? These are a couple of factors that must be considered before replacing the filters.

For instance, if you do not change them on time, then it is surely going to affect the performance of the system and decreasethe qualityof the indoor air. On the other hand, if you change them before they are defective, then you’rethrowing away your money. Therefore, it is importantto knowthe exact time of replacing your filter.

The HVAC filter replacement depends on several factors. When youpurchase an HVAC filter, the sellers will advise you to change it after an interval of 30-60 days. This is a significant rule of thumb, and it can help youto remember the exact time, but it is not necessary that one needs to change it within the mentioned time frame. Here are the reasons why:

The quality of the surrounding air matters

The replacementperiod varies from place to place. For example, if youlive in alesserpolluted area which confronts less pollution, then you can change it after 3-4 months. On the other hand, if you reside next to industries or dusty roads your filters will need to be changed very often.

It depends on whether youhave pets in your home or not.

A suburban home without pets can replace HVAC filters after 90 days, whereas a vacation home with few occupants and without pets can change them after 4-5 months. One might think that pets can be ignored, but the fact is that pets, especiallydogs and cats, have a tendency to shed. The pollutants, also known as pet danders, can quickly clog the air flow.

Presence of sick individuals in homes

Allergy is another crucial factor to consider. If any member of the family suffers from asthmaorisproneto dustparticles, then you need to change filters often to ensure only the cleanest possible air circulates the house.

After summarizing all the above factors, the following conclusions can be figured out:

  • A house located in the suburbs without pets or allergies needs filter replacement after 5-6 months.
  • A suburban house with pets and allergies needs to replace the HVAC filters at regular intervals of 3-4 months.
  • A house located in the main town without pets or allergies should go for replacement after 2-3 months.
  • If we include the pets and allergies in the previous point, then the replacement of HVAC filters should be done within 1-2 months-and sometimes a bit earlier.

A home cannot be healthier without HVACs. Always purchase the best furnace filters, so you don’t have to struggle with breathing problems or frequent filter changes.
