What the PARTU BS-07 Was
The PARTU BS-07 was a tall, slim purifier with seven changeable night-light colors. The older review said it measures 15.3 by 6.9 by 6.9 inches, weighs about 6.5 pounds and cleans the air in four steps. It was said to be very quiet at about 25 dB. The old Amazon link opened a search page, and no unit listing for the BS-07 can be found now.
Looking ahead, small night-light purifiers like the PARTU BS-07 sell well for a season and then vanish. The old Amazon link for the BS-07 was a search page, and no listing for the unit turns up now, only filters from third parties. The catch is that owners have little to go on when the filter runs out.
What the Older Review Said
- Filter. A five-layer filter with a HEPA layer rated at 99.97 percent, to be changed every 6 to 8 months.
- Light. Seven colors. Hold the light button for 3 seconds to turn it off.
- Noise. About 25 dB.
- Airflow. 129 CFM, said to cover 222 square feet at five changes an hour.
- Status. The older review already said it can no longer be bought.
The risk to watch is the filter fit. A PARTU filter sold by a third party may not match the BS-07, and a poor fit lets air go around the filter. The older review also claimed the filter turns the air 85 percent pure, a phrase that does not match a test. Expect more cute purifiers with vague claims. Look for a CADR and a True HEPA rating, and check the filter size before you pay.
CADR and Real Room Size
At 129 CFM, a 222 square foot room with an 8 foot ceiling holds 1,776 cubic feet, so one air change takes about 14 minutes, or about four an hour. That is close to the five an hour in the older review, so the claim is only slightly generous. For five changes an hour, plan on about 195 square feet. See what CADR means.
Filters and Fit
With the unit gone, a replacement filter is the only part still sold, and third-party filters vary in fit. Check the size, and read the air purifier filter replacement cost guide before you buy. Do not reuse a filter past 8 months.
What to Buy Instead
The older review pointed to the AirDoctor 2000, the Levoit Core 300, the Oransi Finn, the Oransi OV200 and the Bissell AIR220 as replacements. See our Levoit Core 300 review and the Oransi Finn review. For quiet picks, read air purifiers for a bedroom.
