There are air purifiers which cost more than you receive in one paycheck. Then there are the units which are really cheap, and cover the immediate space around your desk.
And then there are other air purifiers that clean a huge area at a reasonable price, like the Surround Air Intelli-Pro Air Purifier. This baby has got six filtering technologies in one and covers a large area (up to 600 square feet). Odor, dust and allergen sensors let you know when certain pollutants are detected, such as smoke, pet dander, dust mites, chemicals, pollen, mold spores and many more.
After detecting them, the Surround Air Intelli-Pro Air Purifier sucks the air into a six-layer filtering system (including the HEPA, germicidal UV, and active carbon filter) which traps any particles and contaminants.
If you are worried about ozone, the electrostatic filter combined with the ionic one in this modeI does not emit ozone and uses ionization instead.
The replacement filters are extremely reasonably priced, but you will still have to take the Surround Air Intelli-Pro Air apart once in a while to clean and put them back apart (though the six filters can be easily removed and reassembled). Sensor technology will let you know when you have to replace the filters.
The Surround Air Intelli-Pro Air Purifier has three sound settings – on low and medium, it is very quiet. On high, it produces noticeable noise which will let you fall asleep (though you wouldn’t put it on “high” regularly).
The simple design of the unit is pleasing, it is quiet and works swiftly. It also senses any dust or odors readily, so when the Surround Air Intelli-Pro Air Purifier will detect something bad, it will increase its flow. It is a great air purifier for the price.
