These authentic Blue Air filters fit perfect and work efficiently at cleaning/purifying the inside air. There are No offensive odors from these filters. Arrived undamaged as a set of 3 for our 500/600 model series. We are satisfied repeat buyers. Best of health to you all!

Perfect fit. Filters really well. I always buy genuine mfg filters; not that much more expensive but I never have to worry. They really help reduce the amount of dust !!!!

If you've got a Blueair Classic 500/600, these are the filters. They're expensive as heck but they work great. Much better than other air filters we've tried. So yes, high price, but reduces my allergies like no other filter. Consider it a 6-month medication that's well worth it and has no side effects (except your insurance probably won't cover it!) Highly recommended.

This review will be most useful for the people that are CONSIDERING a 500 or 600 Series Blueair Air Purifier. I say this because if you have already purchased one, you really don't have choices as far as replacement filters go. These are going to be the best fit and engineered specifically for the air purifiers so it's this or lower level filtration with aftermarket generic filters. I read that Crucial Air makes one but don't fit correctly. Since the money spent in the long run is in replacement filters, the reviews for these filters would ideally be read prior to purchasing the purifiers themselves. I had purchased the Blueair 605 air purifier, which works well. But these OEM replacement filters are bittersweet as far as the value of the purchase goes. and hence a 4 star rating. First and foremost, these are generally $79.99 wherever you go, unless purchase with a 20% off coupon at Bed Bath & Beyond or with a coupon at Kohl's . com (which depending on timing and availability could be up to 30% off). The BB & B coupons are harder to come by...try using an unregistered email address and sign up for emails to get a new coupon. As long as you show the store clerk confirmation of sign up, they will usually give you the 20% off without having received the official coupon. Kohl's best discounts are readily available on their website or on coupon sites used in conjunction with your Kohl's account. Those are the best deals as far as these filters are concerned. The only reason why I bought mine here was because I had a giftcard. These will fit as well as any filters would and would be the benchmark standard as far as filters for these purifiers go. I read reviews about aftermarket filters made for the 500-600 Series and they didn't fit well. Fitment is important because with air purifiers, you don't want air-bypass, meaning you don't want air to go AROUND the filter and be blown out of the purifier unfiltered. So there really isn't much of a choice as far as quality filtration replacements go. The reason for the 4 stars (as opposed to 5) is that the longevity won't generally be 6 months if running 24/7. Blueair advises on changing out the filters 2x per year. Although it depends on how contaminated your environmental air is and whether or not you run the air purifier continually, my experience and speculation is 3 + times per year for clean filtered air. The polypropylene media is fairly thin, meaning that contaminant load capacity is lower than required for just 2 filter changes per year. Yet this material minimizes the filter material from becoming a contaminant which is a good thing. Average quality air purifiers tend to use fibrous media material for filters and they become airborne contaminants as they age. These filters are designed to work with the electrostatic charging mechanism of the air purifier (negatively charges the particles which then stick better to the filters) allowing for capture of 99.97% particulate down to 0.1 microns. Not all air purifiers work this way and they generally catch the industry standard of 99.97% of particulate down to 0.3 microns. I've read reviews and the repeated message is that the filter material had decreased over the years. At close to $80 a pop x 3 changes per year, you are looking at $240/year msrp. Take 20% off if getting a deal at the aforementioned retailers and it will still be $192 + tax / year. There are 3 filters in a pack and most other quality air purifiers have 1 thicker large filter and possibly 1 activated charcoal filter which are recommended to be changed 1 to 2 x per year. It's impossible to do an apples to apples comparison because other brands have filters that have more media but at a higher replacement price and still others will only have 1 filter to replace. From prices seen for other brands' replacement filters and frequency, these prices are average. Other high end brands such as IQAir or Airpura only require 1 filter change recommended at roughly $100 - $150 and could cost less per year. If considering the purifiers that these fit into, these replacement filters will cost you a little bit more annually than other quality brands due to 3 changes/year. But if you find the ability to capture a majority of contaminants down to 0.1 microns in size, you won't go wrong with the air purifiers that these were made for. And if you already have the 500 or 600 Series Air Purifiers, others have said that fitment of generic filters are problematic so this would be the best choice. If you found this review helpful, please let me know!

I love these OEM filters. Perfect for BlueAir Air Purifiers.

So glad I got new filters. The old ones were really dirty.

At last, I pulled the BlueAir out and changed the filters. House odors were gone in a couple hours, and his cough and my sneezing abated. You can-which I did last time, vacuum the filters for a little more use. These do last, tho, 6 months if used continuously. In our current stick built house we just use it occasionally, more or less continuously in our previous home, a doublewide. I wouldn't take a chance on anything less for my BlueAir. These filters are the real deal. There is an initial solvent type odor which dissipates after a couple of days. I think this is part of current manufacturing processes, tho, because we had the same thing with our replacement filter for our heat pump this fall. Next time, I'll give them a chance to outgas a little before I use them.

These are perfect replacements for the filters used by BlueAir 500 series air filters. This particular device uses three at a time, this three pack works to do a full filter replacement, which you should do every six months as indicated by the filter replacement light. They work well, and pull a lot out of the air.

I can evaluate this Accessiores as it’s not fitting in my blueair 680i has different fillers

Good packaging，Waiting to use....

Very happy to have clean filters. They were very easy to install. But FIRST, remember to clean out all the accessible vents - I vacuumed and wiped them down. Now we are breathing fresher air. Thank you.

Effective filter that lasts longer than the recommended 6 months eg for animal allergy mitigation. Too expensive for so frequent replacement for this purpose.

Too expensive for folded card, but at least they work.
