Blue Air 403 Special Features

Design

As of Swedish origin, Blue air 403 can boast a solid shape, which naturally fits into any space you allocate it. Another big advantage is galvanized steel construction so that people who are sensitive to off-gas will not be subject to any harm. The inner surfaces are produced from synthetic materials which prevent the growth of various bacteria.

Low noise level

Blueair 403 is a HEPA Silent air purifier. Even when it works at full capacity, you will hear a very delicate noise only. Though a lot of customers report they use the top speed as they find medium mode is not enough for their space.

Filtering potential

Due to the unique patented HEPAsilent technology, Blue air 403 minimizes the harmful air content to almost 0%.

5 Stage filteration

First three stages make up the initial process, during which the contaminated air is imbued a negative charge. All the negatively charged particles are caught by a polypropylene filter.

The last two additional stages of filtering ensure all the impurities are removed. Blueair added filter to cope with bigger particles of home dust (like mold, pollen, etc.) and SmokeStop Filter (activated carbon filter) to fight smoke and odors.

AHAM

Blue air 403 was tested and certified by the Association of Home Appliance Manufacturers (AHAM) for room size of 370 square feet. The Clean Air Delivery Rate (CADR) is:

  • 240 dust
  • 240 smoke
  • 240 pollen

Air Change Rate (ACH)

HepaSilent Technology

Blueair invented a hybrid filter structure with both electrostatics and charged media filters to get HEPA-like effect with less use of energy and high carrying capacity.

3-stage filter thanks to the process of catching negatively charged peculiars make unbelievable work of cleaning the air with 99.97% effect. Three successive texture fiber layers serve to keep the particles inside. Blue air 403 does not involve any chemicals while air cleansing process due to the innovative materials used in its construction. Polypropylene deals with 100% of any bacteria growth.

HEPA Silent technology of BlueAir 403 allows careless filters usage since there is no need to clean them all the time. Normally it takes 6 months before replacement. However, if you don’t smoke or have no pets the filter may serve up to 1 year. Anyway, there is a little clock that informs you when the due date arrives. Blue air 403 is recommended to operate 24 hours every day.

SmokeStop Filter

Those who are concerned about struggling with smoke and odor are recommended to use SmokeStop filter.

This filter has already won a reputation of a strong and reliable odor and smoke fighter. It is filled with 3 pounds of coconut husk processed in a special way that deals effectively even with tough chemicals.

You can utilize the same filters for the whole 400 series. Blueair brand filters are the best and we don’t recommend using analogs.

No Pre-filter

Blueair 403 does not include a pre-filter function. The inner space may get dusty and cleaning it on a regular basis is strongly recommended.

Find a spacious area for your 403 Blue Air cleaner as its dimensions are: 23″ x 20″ x 11″ inches and weight of 33 pounds with no wheel support.

Some reviewers report that the cord would be more comfortable to use if it was a bit longer than 5 feet.
