Honeywell 50250-S Air Purifier Review

Honeywell 50250-S Air Purifier


Honeywell 50250-S air purifier is one of the most effective in the middle price range ($100 – $200). It is recommended for rooms up to 390 square feet (36m2). The 50250-S has a 360-degree air intake.

Design, size, placement

I am not a designer, but this air purifier looks very simple designed. Looks like washing machine drum. 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 heavy – weight 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 air purifier as you want, but for proper air flow, 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 360-degree HEPA filter and around it is pre-filter.  Pre-filter prolongs HEPA-filter life by removing large particles and it helps reduce common odors. 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 virus.

So 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.


  • 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 – very useful 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

Noise level

Noise is the biggest issue for this air purifier. It is really loud on 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 to use it in other places such as kitchen, living room, basement etc.


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 regular ceiling height is 8 feet. 390×8=3120 cubic feet.

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

·     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.

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 pre-filter clean 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 very easy. You just need to unscrew big nut below air purifier.

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


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

My name is Ryan. I have had a hard time dealing with my allergies. Happily, I found that an air purifier was effective to ease my allergy symptoms. I spent a lot of time researching the best air purifier. I know how hard it can be to find the suitable one.

During the reading period, I also read a lot about humidifiers and dehumidifiers. I learned the mechanisms behind the technologies as well as the manufacturers and organizations within the industry.

I now feel convinced that I have built a guide that shows you all you need to know about air purifiers, humidifiers, and dehumidifiers. So I came up with the idea of creating this website.
