Design and build quality

At 20.8 x 71.9 x 28.2 cm (8.2 x 28.3 x 11.1 in), Bionaire BAP825WO-U has the shape and height of an full-sized air purifier including its 5.17 kg (11.4 lbs) weight. It might not be the most striking air purifier, the white color housing does feel smooth and clean compared with other similar air purifiers. Standard easy-to-use controls are located at top with long air intake/ outtake occupying the rest of the body. Included in the package is a HEPA filter and Arm and Hammer Carbon deodorization filter that is both upgradable.

Airflow performance and applicable area

For a tower air purifier, Bionaire BAP825WO-U applicable area is better than its closest competitors at 17 m2 (180 sq. ft.). Unfortunately the applicable area is still insufficient to be placed at master bedroom or living hall. Operating silently in the background, Bionaire BAP825WO-U CADR is rated at 110 cfm for dust, 110 cfm pollen and 116 cfm for smoke.

Final thoughts on Bionaire BAP825WO-U

From the first impression Bionaire BAP825WO-U is pretty much the same air purifier as you would find in other tower air purifier. Upon deep inspection, Bionaire BAP825WO offers slight bump in overall performance as you could see in the specification above. Is it enough to make any difference though? Quickly frankly no. The enhanced performance plays little or no role in this air purifier class. In conclusion, Bionaire BAP825WO-U is a capable air purifier within a segment that has plenty of options.

In conclusion......

  • Low price tag.
  • Optional ionizer.
  • HEPA filter.
  • Carbon filter.
  • Limited features to play around with.
