Bionaire BAP9240-IUK Air Purifier, Silver

Product information

This neat air purifier from Bionaire combines HEPA filtration with an inbuilt ioniser for the ultimate in compact air treatment.

Dirty, dust laden air is drawn through the front of the Bionaire BAP9240-IUK and through the multi-stage filtration system.

  • The washable foam pre-filter captures larger particles and extends the HEPA-type filter’s replacement cycle
  • The HEPA-type filter entraps 99% of all smaller visible and non-visible particles down to 2 microns in size
  • The independent ioniser naturally improves performance and helps freshen the air

The rugged motor has been designed to give many years of use and there are 3 settings, the lowest being perfect for quieter operation (such as in a bedroom). A filter service indicator eliminates guesswork by letting you know when it’s time to replace the HEPA-type filter.

The versatile Bionaire BAP9240-IUK can even be placed either upright or on its side, flush against the wall. Finally, the independent ioniser, when turned on, releases negative ions into the outgoing filtered air to help the air purification process.

Q & As

Rated 4.4 out of 5 by 23 reviewers.
Rated 4 out of 5 by good quality for the price Only been using this for 3 weeks but it definately does improve the air quality. We live in an area surrounded by fields and beech trees and the pollen affects my 3 year old so that he coughs constantly at night. There has been an improvement and we are in the middle of harvest so fingers crossed this was a good buy. He isnt particularly noise sensitive which is a good thing as on the lowest setting it does produce as much noise as say a desk fan. 17 November 2015
Rated 4 out of 5 by A very good machine. This is a very worthwhile purchase. It really makes a difference to the air quality, is small and quiet. Better than some larger competitors. Recommend for allergy sufferers and for those who are disturbed by cooking smells. 20 October 2015
Rated 5 out of 5 by Really good value Ioniser and an air purifier for the price of one. Very good as we live on a main road in Central London and it really makes a difference. 04 August 2015
Rated 5 out of 5 by does what is said on the box This was a gift to my parents, they have been very impressed so far, there are no traces of cigar smoke, which is is a strong smell to tackle. I would highly recommend this. 14 July 2015
Rated 5 out of 5 by Fresh air I must admit that I am really impressed with this air purifier. I have a parrot which creates a lot of feather dust along with the normal dust problems and on starting using this Purifier I noticed that dust problems had reduced greatly. Along with filtering nasty niffs this is a very useful tool. Worth every penny! 14 April 2015
Rated 2 out of 5 by poor Far too noisy for the bedroom.or the sitting room if you are watching TV I would have liked a silent ioniser option as well.Just use when i'm out of the house. 17 February 2015
Rated 4 out of 5 by Great machine but too loud for the bedroom during sleep It truly does work very well and helps to clear the air making a noticeable difference and calming irritated noses. But after weeks of trying even on setting 1 of 3 we find it too noisy to sleep with it running. It needs a 0.5 setting realy. A good solution is to turn it on for the evening to clear the room before sleep. 02 December 2014
Rated 5 out of 5 by Excellent My husband suffers from various kinds of allergies (dust mites, mold etc.). This allergy triggers Allergic Rhinitis which if not sorted within day or two transforms into severe Asthma. This created quite a havoc in our lives till the day this machine arrived. Now, whenever there is a slight allergy reaction, on goes this machine and within few hours the impact is visible. We have got our lives back all thanks to this. Hence, cannot recommend this machine enough for a allergy sufferers and amazing value for money. 23 August 2014
