This new slim version of the classic 203 Smokestop air purifier effectively removes tobacco smoke, Traffic Pollution, fumes, chemicals and odours better than any other brand we know of. The patented hepasilent filter also removes other pollutants such as allergens, pollens, mould spores, dust and pet dander. We think its the ideal companion particularly for anyone who suffers from Chemical Sensitivity or wants protection from smoke and odours. 
The new Blueair 203 Slim Smokestop™ Air Purifier.
The Blueair 203 Slim is the updated version of the classic 203 which now boasts an even thinner and more refined profile. It delivers odour, fume, chemical and allergen free air in rooms up to around 25 square metres. The combined qualities of active carbon filtration to remove heavier odours, fumes and VOCs (including tobacco smoke and traffic pollutants ), and HEPASilent™ filter technology to remove over 99.97% of airborne allergens down to 0.1 micron makes the Blueair 203 Slim Smokestop Air Purifier the most accomplished small room air purifier we have ever had.
Small, Powerful and Very Quiet.
The unit packs a complete, high-performance air purifier into a beautifully compact design that’s incredibly quiet. Although its lowest in class noise levels make the 203 Slim ideal for bedrooms, it is also perfect for other small areas and work spaces to get rid of airborne allergens like pollen, dust, smoke and mold spores.
Zero Ozone
Ozone is recognised as one of the main triggers for aggravating respiratory problems. It is recommended that when choosing an air purifier you should always try to narrow your search down to only those that offer genuinely ozone free performance. The Blueair 203 Slim is officially certified by the California Air Resources Board. Only air purifiers officially certified by the CARB can use the Zero Ozone logo on their products confirming they have been tested and proven to comply with all US federal Ozone emission limits.

Award Winning Swedish Design plus 5 Year Warranty.
The union of visually pleasing form and effective function is a hallmark of Swedish design, and Blueair is no exception. The 203 Slim is designed for maximum performance in small rooms. The Swedish design is not only attractive but built to last. Blueair are known for their durable construction that is made of galvanized steel and is powder coated for durability and environmental protection that produces no chemical off gassing. The reliability of Blueair purifiers is such that every unit sold in the UK now comes with a full 5 year warranty. The air purifier housing itself is very easy to clean, and won't pick up grime and oily stains the way that many plastic units can.
How does it work?
The Blueair 200 Series Air Purifiers use a high performance fan motor to draw vast amounts of polluted air through a steel grill on the back of the machine and into the patented design Hepa filter. The filter then traps over 99.97% of airborne pollutants down to 0.1 micron in diameter. Unique flow characteristics through the filter enable the 203 to remain ultra quiet whilst processing high volumes of air, even on lower speeds.
Tobacco Smoke
If tobacco smoke is part of the problem in your home, then this version is definately the one for you. The SmokeStop filter is made from progressive carbon with a honeycomb-type structure that improves airflow and has hundreds of odor and gas absorbing carbon pellets. The filter contains 2.0 lbs of coconut shell activated carbon impregnated with a 70/30 blend of Potassium Hydroxide (KOH) and Potassium Iodide (KI). The carbon eliminates volatile organic compounds (VOC), which are responsible for odors. The SmokeStop filter is recommended for use in rooms where heavy gaseous pollutants such as cigarette and cigar smoke or other VOC's are present.

*AHAM
AHAM certified room size is the size of room in which the air purifier can provide a full five air changes per hour. Therefore refreshing all of the air in the room through its filters once every twelve minutes.This is more relevant than 'maximum' room size which does not reflect an air purifiers genuine effective capability. Always be sure to only use the 'AHAM certified' room size for true comparison purposes.
**CADR
CADR stands for Clean Air Delivery Rate and is an actual measurement of the amount of filtered air provided by the machine.This is the only true way to compare like for like between air purifiers when assessing how powerful they are. CADR is not the same as air volume which will always appear higher due to the fact that it is only a measurement of the units fan power (with no filter Installed).
***Carbon Filters
Carbon filters remove chemical fumes including VOC's, traffic combustion gases, pet odours, tobacco smoke and many more gaseous pollutants.However not all carbon filters are the same. Basic carbon 'sheet' filters are generally lightweight and have little capacity to adsorb these pollutants effectively. On the other hand filters containing actual carbon 'granules' are infinitely more effective and should always be chosen over carbon sheets where the most effective gaseous pollutant removal is required.

I got this because my son and his girlfriend are staying with me and they both get horrible hay fever. This fantastic gadget has changed all our lives, they are not so irritated and miserable because of the hay fever and I am not so irritated and miserable because everyone is in a better mood ,so joy! I live in hope that it will do the same for some kind of allergy I get in the winter from wood smoke or mould spores from wood it is looking extremely hopeful.
We purchased the Blueair 203 in response to our ground floor neighbour chain smoking most of the evening/night. My partner already has COPD and was spending much of the night coughing in response to smoke from downstairs. The Blueair seems to do a very good job in the living room so we purchased a second unit for the bedroom. They work well reducing smoke smells, are very quiet in use and do not take up a great deal of space. Well recommended for anyone in a similar situation.
I’ve only had the blueair 203 Slim smokestop a week and it’s already improved things in my bedroom. I wear a heart rate tracker and this my heart rate has come down hugely and my Heart Rate variability has increased which is a measure of better health. I feel the wheeze and tightness of my chest has reduced too. Very happy with this product! If only the neighbors next door would stop chuffing then things would be on point!
We bought this appliance as I am a smoker and we wanted cleaner air specifically in the sitting room and it works
