How often do you have to change this filter on the 5300 model
66370
Prefilter: Directions say every 90 days. I run my filter 24/7 and need to change the pre-filter every 60 days.HEPA filter is supposed to last 1 year. I change mine more often due to severe allergies and chemical/fragrance sensitivities; mostly due to scent.

It depends on how much stuff you have in the air (I have a lot!) but the recommendation is to replace the black filter every 3 months and the big white one annually.

The manufacturer suggests that you change the carbon filter every 3 months and the Hepa filter once a year. The 5300 comes with a Hepa filter and 3 carbon filter in the box.

I change the black filters about every 3 months. The hepa filter about every year. But the hepa filter needs to be cleaned. I clean mine 3 times a year. use a soft brush and then by water. Do not use any soap, just water

Printed on the edge of the filter: "Change every 6 to 12 months - more often if the filter appears dirty." My HVAC person recommended every 6 months.

It depends on how soon your scale build up on the filter. I change mine once a month from November to April.

I have the 28" one and just changed the filter for the first time after 10 months.If you vacuum the filter once a month it lasts a little longer.

I change mine on average every 4-6 weeks. We have moderately hard water and it gets progressively crustier at the top as time goes by; this reduces its efficiency in humidifying the air. You will know this is happening if it uses less and less water even on the high fan setting.

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.

The unit has a timer that reminds you to change the filter every 6 months. I changed the filter for the first time this month (I've only had my GermGuardian 6 months) but after I did I realized the filter wasn't all that dirty, probably could have easily been wiped off and would have lasted at least another 3 months. We have a large dog but live in Seattle where there's not a TON of dust in the air. We run it 24/7 on medium.

The company that installed my new system said that this filter would last one year. But when they came out to do an inspection after one year, the guy said that I should have changed the filter earlier. I now change the filter every six months. So far, that seems to be about the right amount of time.

That's hard to answer. It really depends on how dirty or clean your air is. The system tells you when it needs to be changed. I actually clean the charcoal filter several times before changing it. The other filters I only change once a year. I hope that helps. :)

Although, I haven't had to change the filter yet, I have had the original filter out several times. it may be a little tight but I just pull it out.

Usually every 6 months or so depending on usage. The machine will tell you when the filter needs changing

When my Aprilaire unit was first installed, I was instructed to change the filter every 6 months. However, the last few times my furnace/air conditioner was serviced, the serviceman suggest that it be changed only once a year. As noted on previous posts, a lot depends on your location, i.e. if you live in a dusty area or a place that has a lot of air pollution, and whether or not you have a lot of pets. The best thing to do, I suppose, is to check the filter every six months. It will be easy to tell whether the filter needs to be changed. I also keep an extra filter on hand for future use. I hope this helps. When my Aprilaire unit was first installed, I was instructed to change the filter every 6 months.

I have only had mine 6 months, but after reading a lot online the recommended is once a year. Also if the water slows going through filter scrubbing with a soft scouring pad will help, but so far I haven't had to do that.

I have a slightly different model that uses the same filter. This filter is nearly the size of the unit, so you only use one. I replace mine every few years. There is also 1" outer filter that wraps around this inner filter that is made of a soft mesh-like fabric material.

I haven't had any problems with mine since I put it in. Mine been in for at least four months now, my old filter in had to clean it every month and half.

Since buying the 530 I backwash less and my filter stays cleaner. I would say yes, cut that filter time.

The water will need to be changed once a month about 25% of the water. The filters last quite a while because the filter system is actually designed for a 5 gallon aquarium. Once you notice the filter over filling that's when you change it
