3M Filtrete Ultra Quiet

• 3M Filtretes relieve the symptoms caused by airborne allergens
• Offer 30% higher CADR* (clean air delivery rate) than an equivalent size HEPA filter so that your air is cleaner faster and you feel better sooner
• Filter out smoke, bacteria, fungus, pollens, virus, pet dander, dust and dust mite allergens so that you breathe clean, healthy air 

The Ultra Clean and Ultra Quiet air purifiers use a Filtrete™ electrostatic filter, which is 99.9% effective at removing pollen, dust mite allergen, mould spores and pet dander. It also captures household dust, bacteria and particles that carry odours and particles that can carry viruses, smoke and smog. Ideal for hay fever, dust mite allergy, asthma, rhinitis and pet allergy.

CADR - Clean air delivery rate 
Some air purifiers have a CADR number which indicates the volume of filtered air delivered by the air cleaner. There are three CADR classifications - pollen, dust and tobacco smoke. The higher the numbers, the faster the unit filters the air and the larger the room size the air purifier will effectively clean.

How the electrostatic filter works
As the air passes through the electrostatic air filter it produces friction that creates a natural electrostatic charge between the polypropylene and the layers of bonded polyester fibres. The electrostatic charge attracts minute household dust and other particles to the electrostatic filters like a magnet. An electrostatic filter is effective at capturing particles down to 0.1 micron. It should be replaced every three to six months (three months of continuous use). The 3M filters are completely ozone free. 

Without even realising it, we all breathe air which contains millions of microscopic dust, pollen and mould spore particles. It’s these particles, along with a host of others, that cause allergic reactions including asthma and hay fever, which affect so many people in the UK today. 

Filtrete™ air purifiers offer first class performance for a range of airborne contaminants. In some recent research by 3M, tests at the University of Reading showed that dead skin cells, dust mite debris and mould spores are “highly prevalent” in our homes. The testing panel were very pleased with the results. One parent stated: 

“I was a bit sceptical at first but now that we’ve had an improvement in my son’s asthma and a reduction in the use of his inhalers I am completely sold on the product.”

 Another commented:

 “My son’s asthma improved to the point where we were able to significantly reduce the use of the corticosteroid inhaler. His dermatitis improved, as did the itchy nose, eyes and wheezing. I think the difference was very noticeable after I sent the filter back for testing. I didn’t have a replacement filter and within 3 or 4 days of not using the Filtrete air purifier I noticed my son was wheezy in the mornings and has needed to use his ventolin inhaler more...”
