Honeywell 50250-S Design, size, placement

I am not a designer, but this air purifier looks straightforward design. It looks like a washing machine drum. The white color makes it easy to merge with the room.

Size is big, height 19in (48cm), width 18in (46cm), depth 18in (46cm). Also, it is quite heavyweight, 20lbs (9kg). But with the built-in handle, it is easy to move it. The 360-degree air intake is a big plus, you can place an air purifier as you want, but for proper airflow, you should locate the unit at least 3 feet (1 meter) from any wall or furniture.

How it works and what sources of indoor pollution destroy

The Honeywell 50250-S uses a fan to move the air. Inside is a 360-degree HEPA filter, and around it is a pre-filter. Pre-filter prolongs HEPA-filter life by removing large particles, and it helps reduce common odors. The HEPA filter is a long life, captures 99.97% of particles as small as 0.3 microns. And it really works – captures dust mites, mold spores, pollen, pet dander, tobacco smoke. It also helps capture certain airborne germs, such as bacteria and viruses.

This unit is ideal for allergy and asthma sufferers, fighting smoke particles, and boosting general air quality. If you have a headache, itchy nose, eyes, cough, this unit will help.

Honeywell 50250-S Features

  • Digital controls – switch for 3 speeds – turbo, medium, and low
  • Filter replacement indicators for both filters. Remember to reset
    them after the filter change.
  • Carrying handle – handy for 20lbs unit.
  • SurroundSeal Technology helps minimize air leaks and ensure that all air that passes through the filter is cleaned of particles and impurities.
  • 5-years warranty

Honeywell 50250-S Noise level

Noise is the biggest issue for this air purifier. It has really loud turbo setting and medium setting. Much quieter on the lowest setting but with this setting air purifier vibrates a
little bit. So you can’t use it in your bedroom. Ok, maybe you can if you have a strong sleep. But I would recommend using it in other places such as the kitchen, living room, basement, etc.

Honeywell 50250-S CADR

CADR – clean air delivery rate.

  • Dust Rating: 250 CADR
  • Smoke Rating: 250 CADR
  • Pollen Rating: 250 CADR

Honeywell 50250-S is recommended for rooms up to 390 square feet.

Let’s say a regular ceiling height is 8 feet. 390×8=3120 cubic feet.

Next, calculate how much time it takes to cover all rooms.

  • To remove dust: 3120/250 = 12.5 minutes
  • To remove smoke: 3120/250 = 12.5 minutes
  • To remove pollen: 3120/250 = 12.5 minutes

In smaller rooms than 390 square feet, Honeywell is even more efficient.

Honeywell 50250-S Maintenance and upkeep

Honeywell recommends replacing pre-filter every 3 months or even more often. It costs around $20, so that’s $80-100/year. When changing the pre-filter clean the HEPA filter.

About HEPA filter thoughts split. But I think that for the best air quality you should change it once a year. You can use replacement filter model 24000, which costs approximately $50, or 3 HRF-F1 filters (one cost $30, so together that would be $90).

Filter change is straightforward. It would help if you unscrewed the big nut below the air purifier.

On it’s highest setting, it pulls 170 watts. That is like a video game console or TV. On the lowest setting, it uses 50 watts that are really nothing.

Honeywell 50250-S Summary

Excellent air purifier under the $200 range. Delivers clean air in 12.5 minutes in the quite big sized room. Easy to use and maintain. A great feature is the 360-degree air inlet.
