The Standard Ultra Clean is ideal for a small to medium sized bedroom, office or living area.
The Ultra Clean air purifiers from 3M use a Filtrete electrostatic filter. They are 99.9% effective at removing pollen, dust mite debris, pet dander and mould spores. The units have three speed settings with a simple control knob and a light indicator to let you know when the filters need replacing. Most permanent and washable filters quickly lose their electrostatic properties through washing and clogging. Filtrete uses replaceable electrostatic filters to deliver the enhanced filtration of an electrostatic filter on a sustained basis.
Compared to a HEPA filter with a comparable room size capacity the Filtrete Room Air Purifiers deliver up to 30% more air circulation, up to 24% higher pollen capture rate and up to 12% higher dust capture rate.
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...”
