Does it have filters that need to be replaced periodically and if so, how often?

There is a pre-filter that you have to change. There is an indicator to tell you when to change filters. How often depends on what setting you run. I run mine at medium 24/7, high for 1 hour after vacuuming. I change filters about every1 1/2 - 2 months. They're not expensive.

Depends on how often you run the machine...I run mine about 12 hours per day and I change the filters about every 18 months.

I bought mine 4-5 months ago and it came with 3 spare filters - not sure if that qualifies as recent

We change ours every 3 months (90 days) - We have a thing set up with Amazon to send us a filter quarterly, we have an extra on hand so after I use the one I have a new one waiting. Ours has a dial on top to tell me when to change (in case I forget)

There is a permanent filter that can just be rinsed and an additional optional replaceable filter that can be used in front of the perma-filter. Not sure of the cost but replaceable filters need to be changed every 3-4 months....additional notes, this unit has a pretty loud fan if used on medium or high speed.

Actually this unit does not have a filter. I take mine apart annually and clean the internal parts with a vacuum and stiff brush and damp cloth. The unit after being used a while develops a dark residue from dust particles that appear to almost have decomposed. The UV bulb is the only item that will need to be replaced about every 1 to 2 years. When your unit stops producing that fresh crisp distinct ozone smell then the bulb needs replacing. Hope this helps.

It comes with filters for the top. I supposed you will have to buy some at some point but it probably depends on how often you use it...Hope this helps!

They usually do. The filters aren't very expensive and you can reuse them several times before having to replace them. Just clean them once a week.

Nope, Ive now had mine for quite a while and everything is working just fine. No filters needed.

I've only used it a few times, but I know it has a Hepa filter that can be replaced when needed. The other filter can be cleaned. Hope this is helpful.

Not very often. When the indicator light came on , I vacuumed the first two filters and put it back in service. Its been running constantly since april on auto. Highly recommended. Its quiet and it works

You don't even need filters. It has a filter basket that you just rinse every time and it is more than adequate. Once a week I run it through the dishwasher.

and usage...if you run it 24/7. I would change every three or four months. Some folks just vacuum the filters. I'm goona try it.)

It comes with a filter in it. They recommend you put a new filter cartridge in about every 6 months.

According to their website, filters should be replaced every 6 months. We've been using ours since 9/2012 and haven't replaced the filter yet. The water is still tasting good. Your water usage would effect how often the filter needs replacing.

Yes it does. It uses two types of filter, one which is meant to be permanent, and one which is meant to be replaced periodically. It comes ready to go with both. In the past I simply vacuumed the replaceable filter between replacing it and that seemed to work pretty well also.

Yes, the pre-filter needs to be replaced every month or two. The HEPA filter material is inexpensive and it takes just a moment clip the fabric and insert it into the air cleaner.
