Furnace/Air Filters Question

[Lee]

How often do you change them? I do it once a month and just read the changing them only at the start of each season is adequate.

Do you change more often if you have pets in the house?

 

[JaniceM]

Unless there are small children, pets, elderly, or individuals with serious health issues, once before the start of the heating season and once after the heating season is over.

 

[Jackie23]

I change mine once a month too, I have bad allergy problems.

Unless your area is exceptional windy and dusty(like ours here) every 3~4 months would probably be fine. Write the date on the filter with a sharpie when you replace the filter, then check the filter periodically for the amount of dust collected.

 

[Don M.]

I change ours twice a year....Spring and Fall. With just the two of us, no pets, and little dust in the area, the house stays fairly clean.

Now I’m embarrassed to say that I don’t know. I really think it’s twice a year. A lot of little jobs I will be learning to do.

 

[MarkinPhx]

Once a month May-October and then only a couple of times during the winter months.

I pull mine out once a month in the winter, and blow them out from the backside with compressed air. The one in the shop depends on what kind of work I'm doing. Replace once a year or so.

It isn't a time thing. On the first of each month look at the filter, when it's starts to collect to much then you will know how look your system filter will need to be changed. Start with a new one then start watching it. Each household will be different. This will be a pain if your filter is hard to get at, but worth it since it will effect the efficiency of your system and will put a strain on it. Which will cost a lot more later. I change my filter every other month, we live on a dirt road and have a cat.

 

[Remy]

I need to go check mine. Two cats, a litter box. I need to change the filter more than twice a year.

 

[Alligatorob]

Probably should monthly, but I usually only do it a couple of times a year. No big problems so far. If you have a lot of dust more often might be better.

I do it twice a year, when I start the heater for the winter and when I start the ac in the spring. That is what my unit calls for but am thinking of doing it more often since I have had a large hairy dog join the family. I know I have to vacuum the intake vents a lot more often. Even the floors need to swept or vacuumed once a day to keep up with the beast. (kidding, he is a sweetheart)

 

[MickaC]

Change mine every other month, in the winter but it collects fast, it’s once a month
In summer, spring, I check them often, and decide then.

 

[dseag2]

Twice a year for the A/C filters. There is no way I am going up into our attic right now when the temps are over 100 degrees. I changed the filter in May and will change it again in September. But I brush my cats once a week.

Check it every month. Usually its changed when it needs it.
