Diva Blue

Original product and a perfect fit. Purifiers all look brand new. Had a slight issue with one of the sleeves but the seller resolved the issue quickly which was greatly appreciated.

Great fit for our Blue air 411. We alternate between this and the original one. The cover is a great fit, very easy to replace and great value for money.

I've had this about a month now and these pre-filters work really well. It does a great job at catching larger dust particles, pet hairs etc In the photo's, I've tried to show the dirty dusty filter, then I've vacuumed a section so you can clearly see the dirt/dust/hair on either side and then the last photo is the fully vacuumed 'clean' filter. I bought this so that I can have the Air Purifier running 24/7. I swap them every 3-4 weeks and wash in the machine on a cold gentle cycle, leave to dry in the airing cupboard. I vacuum the pre-filter every week (in-between washing) and I'm amazed at how much dust/hair accumulates over the surface of the pre-filter. I have 2 large golden retriever's and these air purifier's have really helped control the dirt/dust in the house and the inevitable 'doggy' smells! They are super easy to fit onto the actual air purifier. The material is very stretchy and so you simply remove the top of the purifier, remove the old/dirty pre-filter and then stretch the new into place. Simple! My top tip is to always vacuum the pre-filter before removing it from the unit. Wash these on a gentle cold cycle and then air dry them. If you do that, they will last a long time.

Fitted perfectly. Good to have a spare so the other can be washed.

Excellent you can get different colour

Fits well looks as good as original works well

After using for some time now it does do the job .. but has a faint constant smell

All as it should be.

BEWARE: This *does not* fit the 411+. (I didn't realize there were two 411 types.) Unfortunately, I didn't read carefully enough. I loved the red. It is not too sheer. Sadly, the 411+ only come in 1 color.)

It's perfect!

Easy to change.

Great product and snuggly fits the Blueair purifier.

Beautiful quality, this cover is really the first line of defense for your air purifier. It captures any larger particles and does some of the work of the inside filter. It's washable, but I still bought several colours so I could change up for a new feel or for different decor, or simply when one is in the wash, I have another on the purifier. I love the colour choices too! Great value and its great to have a spare on the go as well!
