Honeywell 50250 99.97% Pure HEPA Round Air Purifier Review

Many people suffer from sinus problems and allergies triggered by pollen, dust, pet dander and the like.  Allergy medication may help in treating the symptoms (runny nose, sneezing, watery red eyes, etc.) but the best thing to do is eliminate the cause.  The Honeywell 50250 Pure HEPA Round Air Purifier is an affordable air cleaning device that will leave the air in your home fresh and pure.

The Honeywell 50250 is equipped with a true HEPA filter that removes up to 99.97% of common airborne pollutants.  It clears the air of dust particles, pollen, tobacco smoke and pet hair as small as 0.3 microns.  As a true HEPA filter, the Honeywell air purifier meets the filter standards set by the U.S. Department of Energy.

Product Description

The Honeywell 50250 is round-shaped, with a diameter of 18 inches.  At 19 inches high, it is quite large so you should figure out where you want to place the unit before purchasing it.  The air purifier has a 360-degree airflow and 3 speed settings.

The Honeywell air purifier comes with a carbon pre-filter to help remove odors and particulates.  The glass-fiber HEPA material removes viruses, bacteria, mold spores and airborne particles. 

An Intelli-check electronic filter change indicator lets you know when it’s time to change the filter.  This product is ideal for larger rooms up to 390 square feet.

How It Works

The Honeywell 50250 round air purifier is a winner for a number of reasons.  It comes with a true HEPA filter that removes air pollutants and allergens such as dust, pollen, pet dander and cigarette smoke.  In addition, it is equipped with an activated carbon pre-filter. 

The pre-filter boosts the effectiveness of the Honeywell by removing odors and volatile organic chemicals (VOCs) that cannot be removed by a HEPA filter.

Compared to similar air purifiers, the Honeywell 250 has a better Clean Air Delivery Rate (CADR) for its price range.  The CADR is a standard used to compare the effectiveness of air purifiers.

This air purifier is well designed, with its 360 degree air intake and exhaust.  The round design makes it effective at circulating air.  The unit itself is sturdy and weighs only about 20 pounds.

At the highest speed setting, the noise level of the Honeywell air purifier is quite high.  You can run the purifier on high for a few hours and then set the speed at medium or low to keep the noise level down while you sleep or relax at home.  The noise is not a mechanical sound but a high air flow sound.
There is a slight vibration at the lowest fan speed.  This is normal and is caused by slow air buildup across the HEPA filter due to the low air intake.  The vibration does not affect the performance of the unit.

HEPA filters have to be replaced, and this is usually the highest up-keeping cost of air purifiers.  An annual cost of about $100 on HEPA filters is the norm.  Filters are usually replaced once every three months, depending on your usage.  The activated carbon pre-filter also has to be changed regularly if you are particular about odor control.

If you come across the Honeywell 50250N or Honeywell 50251, they are basically the same model.  The only difference is that they come with a permanent lifetime HEPA filter, which can save you a lot of money.  In reality, however, the permanent HEPA filter is good for only 5 years after which it has to be replaced.  A permanent filter must also be vacuumed and cleaned to regenerate it.

The Honeywell 50250 HEPA round air purifier is inexpensive at around $160.  For an air purifier that costs less than $200, it works very well indeed.  It is powerful, easy to maintain and portable.  The 360 degree air intake and air output makes it more efficient.  Replacement parts are easily available and it comes with a 5 year limited warranty.


The biggest drawback to the Honeywell is the noise at high speed setting.  It also has high power consumption and the design is strictly utilitarian and not stylish.

What Consumers Say

Consumers are mostly satisfied with the Honeywell 50250 and give it an average score of 4 stars out of 5.  For its price, this air purifier does a very good job.  Individuals who are sensitive to pollen, dust and other allergens notice that their allergies disappear or are very mild when they use the Honeywell.

The main concern with the Honeywell 50250 air purifier is the noise when operating it.  Some people find it too loud, although others say they can live with it.  The low fan setting provides a white noise that some people find soothing.  Naturally, this is a matter of personal preference and you will have to decide for yourself whether or not you can tolerate the noise.

On the whole, however, most consumers give the Honeywell Pure HEPA Round Air a thumbs up.  It is affordable, performs very well and comes with an excellent 5-year warranty.
