Key Features of the Blue Pure 221+

1. The Blue Air Purifier has a Three Stage Filtration System

The Blue Pure 211+, has a simple three stage system which you can also see in the image below:

Pre-filter – The fabric pre-filter of Blue Pure 211 sits outside of the air purifier and this is designed to catch the large particles in the air. This filter can be cleaned by either washing or with a vacuum cleaner. 

Particle filter – Instead of using a True HEPA filter, the Blue Pure 211+ uses a polypropylene fibers filter. This captures 99% of all allergens like dust, dust mites, pet dander, pollen and fungi.

Activated Carbon Filter – This final stage is sited inside the particle filter and is highly effective against smoke, odors and gases. The filter is also effective against Volatile Organic Compounds (VOCs) a whole range of chemicals which may have both short term and long term health effects.

2. Very Easy to Use

You can’t go wrong with a one-button control! This makes the Blue Pure 221 very easy to use. All you need to do is plug it in and turn it on. When you press the button for the first time, it automatically sets itself to the recommended operating speed. If you need to make adjustments then it’s just as easy to set-up.

3.  360 Degree Operation

Many air purifiers only draw in air from the front. The Blue Pure 221 has 360 degree intake, drawing air into the filter from all four sides. That means that no matter where you place it, it’s going to be totally efficient.

4.  Coverage

Did you know that indoor air is up to 5 times more polluted than outdoor? The Blue Pure 221 is capable of cleaning the air in a 50m² room 5 times per hour. If your room is smaller, then that just means that air gets cleaned even faster and more frequently.

5.  Design

Uniquely customizable, the Blue Air purifier has optional fabric pre-filters available in a range of colours. This is pre-filter catches larger particles which then extends the life of the main filter. Simply pop it in the washing machine or give it a vacuum when it becomes dirty.
