Air Filter Change Recommendations
One of the biggest things that can impact your home’s indoor air quality is the HVAC air filter. No matter what type of AC air filter your unit uses, it is imperative that you change it regularly or wash it according to the manufacturer’s recommendations (if it is a washable air filter). There are several factors that can impact the frequency which you need to replace your air filter; they include:
- Pets – Do you have any pets? If so, how many?
- Occupants – How many people are occupying your home?
- Type – What kind of air filter are you using?
- IAQ – What is your ideal indoor air quality?
- Pollution – Is there a lot of pollution outside the home?
The general rule of thumb is that you should replace furnace HVAC filters every 30-60 days. But, as we’ve indicated above, this timeframe might change depending on your individual situation. Keeping the above factors in mind, we’ve come up with some guidelines and scenarios that may impact when you want to change your HVAC filter.
Furnace Filter - HVAC System
If you live by yourself (or this is your vacation home) and you don’t have any pets – you can change stretch out your filter changes a little longer. You still want to check the filter every 3 months to make sure it isn’t clogged or dirty.
If you have an average size family (and home) and you don’t have any pets – you can change your HVAC filter every 2-3 months.
Do you have an indoor dog or cat? – change your furnace filter every 30 days.
If you suffer from allergies or you have multiple indoor pets – change your HVAC air filter every 25-45 days.
Other than following the general guidelines above, you may want to check the status of your home’s air filter if you notice that your HVAC system is no longer performing as well as it used to, or you notice that your indoor allergies have gotten worse.
By following the simple guidelines for replacing your HVAC filters, and by adhering to the manufacturer’s recommendations, you can ensure that your home’s indoor air quality remains at an optimum level.
