how often do I need to change filter bags?

Really depends on the use. The bags are really small. But I had cleaned 4 floors approx. 2000-3200 sq/ft and a complete construction clean with this (4800 sq. ft) before I had to change my first bag. I was pretty surprised.

I bought it for my Dad, who lives in a different state. He loves it, and says the bag lasts a long time - much longer than normal canister bags. A light comes on when it's full. The bags are much stronger than traditional bags, too. He has a 3 bedroom Cape house with rugs and hardwood. No pets, though. Hope that helps!

Changing the filter depends on how often you use the coffee machine. We change ours about once every 18-24 months because we do not use the machine very much (about 2 - 3 times a month). You could also gauge the changing time by how the coffee tastes. If you make it the same every time and you notice it tastes a little different, you probably need to change the filter.

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 these filters should be changed out every 6 months. Just because of how much filth they pick up from vacuuming.

According to the owners manual, both filters need to be replaced after approximately 20 dust bags have been used. The manual also says that the micro-hygiene filter can be changed when it becomes extremely dirty or clogged. I've only had my vacuum a few months and haven't had to replace a bag yet.

I think from 80 days the filter starts to dry out. Manual recommends another thing but I would tell you refill when the bag is dry.

The Eureka Optima Bagless Upright comes equipped with the filter, but you will need to actually replace your filter every 3-6 months depending on how worn from use it becomes. Just remember to maintain your filter between replacements by brushing the soil off perhaps with a clean, dry paint brush or using a brush attachment from another vacuum source to clean your filter whenever needed.....J.

First of all the cleaner the filter, the faster it filters. When it is new, it will filter the full amount in about 6 hours. After the filter gets some use, it will take a bit longer. I take mine out and wash them every 3-4 months and change them once a year.

I change the filter for our pooch about once per month. Depends on how hard the water is where you live. If you use filtered water it should last much longer.

I changed mine at 3 months, mainly because I noticed by the contents of the bin that the airflow appeared to have decreased slightly. I used to change filters once a month before switching to the purple filters. I highly reccommend the -21 filter and brush upgrades.

Membrane every 2 years. Filters need to be changed more often--according to the amount of use.

As I use only distilled water, I usually change my filter approx. every 3 - 4 months. Hope this is helpful to you.

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.

Naturally, it depends on what you put into the trash receptacle as to how bad the odor is or how bad it will get. We replace our filters about every 3 months and get along real well the odor control.

It depends on how often you run the unit and how much dust/allergens it's filtering out of the air. If it is always running then generally the filter should be replaced every 6-8 months.

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.

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.
