You get enough for the first year with the unit. One type is replaced about every 3 months ,the other one once a year. This was a gift for my sister with severe asthma. She uses it her bedroom and says it's the best gift ever for her. She feels like she can sleep peacefully now.

I was running the air purifier 24/7 days a week for 5 months during our winter, and by the 6th month I had to replace it. not to say that is what may happen to you, but something to consider if your planning on running it that way. I needed to run it all the time since my allergies are worse during the winter. it also depends where are how much dust is pucked up in thearea where you place it.

I am not sure exactly how long they last, however, we have used ours far longer than the projections and the filter worked great. Sorry i cannot be more exact. I just recently bought the first full filter set. It helps if you clean the outer filter often.

No real experience with this model. With other types it all depends on how long you run it and how dirty the air is. I have had hepa filters go from three months to a year. Vacuuming the hepa also helps.

It comes with 2 filters that last about 6 months. You have to replace them with new ones ...bought on Amazon. We still love ours almost a year later.

About 3 weeks. I smell them everytime I change the water. It is obvious when the smell changes, change the filter.

I can't tell you how long it lasts since I am still using it. Be sure and get the pre-filter which will keep most of the dirt off of this filter.

I only use it for about several weeks, and it works well for now but i don't know how long it lasts. As for the filter, I may try to buy a new bottle considering the price of this bottle.

Length of time. I think it's one year. It's just a stick on timer. It gets no info from the filter.

I don't have the product literature in front of me, but usually these things can go 3 months or so before the filter is changed out, especially if the water is kept clean. Filter longevity will depend on your water and how much stuff the pets might drag into it.

It is a cloth filter which can be cleaned manually. It can therefore last for years. Cleaning it manually takes about 5 minutes and is messy and dusty.

Every 6. month's but make sure it's the correct filter because the one I. ppurchased in December was shipped with the wrong filter it blew dust out. replaced with right filter this is my second one. That's why I purchased this one, the last one lasted fir 10 years. It ran 24 hours 7days a week nonstop.

Eventually the filter will need to be replaced. As long as you take care of it it last a long time.

It really depends on your water. The higher the number from the wand (ppm) of your water the faster the filter will need to be changed. Our water unfiltered is about 34 and after 5 months we are on the same filter. We use at least two pitchers of water each day, usually more.

I clean my Filter every Week, just to keep it clean. I soak it in Vinegar and water 50/50 for about 10 hours.

They last a very long time! I use this purifier in my office that is in a warehouse which is very dusty and has a lot of traffic. I run once or twice times a week and over weekends. I went to change the filter for first time after nearly a year and filter was still pretty clean.

Manufacturer says 1 yr. I doubt if we have to replace ours at 1 yr, just vacuum the pre filter monthly. That will make a big difference on how long the filter lasts.

I replace mine every three of four months. Could go longer, but we have a central well in our neighborhood and often get sediment in the lines that has to be flushed out (causing my filter to clog). Generally, activated charcoal filters should last 4-5 months.

If you're using tap water then know if it's alkaline. The higher the alkalinity, the more often you will need a filter, every 3 to 6 months. If you use filtered or reverse osmosis water, then a filter will last 8-12 months. This also allows the mist to circulate in the air longer. This is what I do and it reduces costs of buying filters.

I change them a little longer that the recommended times. We use the filtered water only for cooking and related things. There are two time frames: One filter will last one year plus and the other two should be changed every 6 months. As I said we try to wait a little longer. Maybe 8 months for the two and 14- to 16 months on the one. It really depends on use and the quality of your water.
