The control screen will tell you when it needs to be changed.... frequency will depend on usage and environment.

I returned my alen A350 after about a week of use because of the high noise level. I recall reading that filter change varies according to use and conditions. Every 6 to 12 months is the norm.

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.

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

My HEPA filter just recently needed to be replaced after eight years of use. I bought it back in 2006. I don't use it everyday - mainly during pollen season (here it lasts 3 months a year, but doesn't always bother me), during forest fires when it is smokey and various other uses as needed.

Only the HEPA filter need to be replaced every year depending on the environment where you are. The others are permanent. Contact the New Shining Image for filter replacement.

Manufacturer's recommendation is 6 months for the odor eliminator filter and 12 months for the HEPA filter. I purchased our Coway in November and haven't changed filters, for everything is working as expected right now.

Our household and environs are so dusty and polluted that I need to check the pre-filters monthly and the HEPAs twice yearly. Otherwise they become so choked with filth that they become ineffective. So while the 3 & 12 month cycles are recommended your mileage may vary.

The Whirlpool E-Console APR45130L comes with the Whirlpool True HEPA filter (Usually change every 12 months depending on usage and the air quality in your home) and it also comes with the Carbon pre-filter that removes odors and catches larger particles like pet hair. The Pre-filter usually needs to be changed every 3-6months and using the pre-filters properly extends the life of the HEPA filter. The purifier also has filter meters that will tell you when it is time to replace the filters. Leave it your own visual check of the filters to tell you when it is time to replace! Hope this helps.

No. A new HEPA filter should be purchased when old one needs to be replaced.

The honeywell unit I have does not require a hepa filter replacement. It only needs to be vacuumed every six months.

I have checked the Hepa filter from time to time. Over the two years or so in service, it still looks brand new. There is another filter behind the dirt catcher that pops out and back in very easily. I usually wash it one a month. Takes less than 3 minutes.

I bought my IQAir filter sometime around April 2010, and have replaced the HEPA filter once. I bought a spare filter in November, but the replacement light has not gone off yet. I usually run the fan at about Speed 1 or 2, and it is usually on 24/7.

The hepa filters do NOT last as long as they say! I must change mine every 3-4 months $$$$

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.
