Twice a year. They really don't get that dirty. Buy a 3 pack at Costco or Sams Club and you will always have an extra one around and cheaper too.

I never change them, I have a guy named Nick who runs around town changing them.

Nicholas Crane I always used to forget to change them. I purchased a whole-house electronic air filter. I have been cleaning it about every six months.

I change the filter every month. I have heard that the correct air flow is very important for the efficiency of the system. I have been told by HVAC service people that the thick filters are too restrictive and reduce air flow.

Every other month and I buy the 3 pack so there's always at least one available. It's important Nicholas!

Good morning Nick. In our home and office, at least once a year, in my vehicles, at least a couple of times a year.
Make it a great week!

Twice a year but should probably be every month since I live in one of the top 5 dirties air cities.

monthly in summer and every three months the rest of the year. We heat with a wood burning stove so our furnace runs very little.

I only use wood heat. There's no furnace in my house so I don't have any filters to change. I'm not joking.

It depends on how dirty the air is. I have an electrostatic air filter and it gets really dusty so I would say every 6 weeks.
