You should change the filters once a month to make cooling and heating efficient.

I think every 30 days is what is recommended; however, I change them every three months throughout the year.

I've found that I have to replace them on a monthly basis to keep them efficient.

Here in the mid-Atlantic states where snow (up to 10 -12 inches at least once a year), cold (below zero a few days), and heat (up to around 100) gives us some extremes, I see these have lasted (have now had two sets each on our SUV and convertible) about one year each pair, which I think is better than other blades which might last only one winter or one summer season. Love them.

It all depends on how much you use them, but for me i use them everyday with high dust content so I replace them every few months

We only used ours during the fall and now winter. We do live in Las Vegas, NV so we'll need to keep an eye on them this summer.

I change mine every 6 to 9 months. It greatly depends on how wet the conditions are, and how good the inside filter does. All depends on how bad the system enviroment is.

I think they officially want you to replace them every 6 months but I usually replace them around once a year. It depends on your usage. I have it hooked up to a below counter ice maker & also a drinking water dispenser above counter. When the water starts running slow on the dispenser I replace the filter.

I usually change them about once a month. I rinse them off when I change the fountain once a week. Sometimes I get longer.

I replace mine about once a month when using the machine. The only reason I can see to replace is that mine get hard water deposits and no longer wick the moisture properly. You may not need to change them as often although eventually they will kind of break down. I am not sure how often the manufacturer recommends replacement. Hope this helps.

Depends on use. I replace mine every 6 months. But I also keep my hot tub very clean and wash filter every month.

I'd say they last a good 18 months or so. Recommend this product, but cover or remove in winter; it will crack with repeated hard freezes.

Not sure exactly, but I rarely replace them, I would say over six months at the very least

Have not had any problems since I put them in couple of years ago. Especially with the amount of snow and freezing temperatures this past winter.

I don't give mine heavy use. they work well for me using occasionally and as needed. Make me feel more secure on icy/snowy surfaces.

I only use occasionally because I'm in Atlanta and the winters are mild. I keep them inside my house in the closet so they are not exposed to harsh weather or UV from sunlight. I've had three sets in twenty five years only only replaced them when they were lost in the move to new place. My first set was in Michigan and my second set was in Japan. Both locations had lots of snow and ice and I worked outside around aircraft on concrete. In Atlanta we have an ice storm once or twice a year. I've never worn out or broke a part and even I had the cost is nothing compared to a broken tailbone or cracked skull. I only use occasionally because I'm in Atlanta and the winters are mild.

I don't see why you couldn't. However, since it is recommended to replace them every three months, I don't know why you would need to...

The answers you've gotten are good and yes, I agree that they are cheap enough to replace daily or even once every other day but I avoid reusing one too long as I'm worried about bacterial and mold buildup from the humidity.

I run mine for one winter on one filter. Start with a new filter every year.
