50250-S has many features, and some of them are very important at cleaning the air at a rapid speed. The filtration system is a standard air purifier technology used in many other models. It uses True HEPA filter as the primary filter as well as pre-filter and carbon filter for removing odor.

True HEPA Filter

True HEPA Filter is the most essential part of the device, also with the True HEPA filter you should see an immediate improvement in air quality. It is powerful enough to remove pollen, dust, smoke, mold, and pet dander from your indoor air. It can capture 99.97% of all harmful particles as large as  0.3 microns. For the most part, people change the HEPA filter every six months.

Pre Filter

Pre-filter captures large particles for quicker removal. Pre-filters are needed to keep the primary filter clean and free from large particles which can be easily removed with a standard filter.

Activated Carbon Filter

Its primary job is to remove bad smells, odor, toxic materials, and other odors that may be in the room. The second-most common type of filter activated carbon which cuts through the air and removes nasty odors. It can remove any kind of smell, including burnt food and smoke. Activated carbon filter also can remove some chemicals and other VOCs.

Low Noise

The manufacturer claims this unit to be 4 times quieter than other popular models.  What this means is that the noise level produced by this unit is 4x quieter than other popular air purifiers. This seems to be a good promise for bedroom work.

Energy Efficiency

This unit is energy-efficient, and Energy Star certified. It can reduce your energy bill and help you support the environment.

High Air Circulation

Nobody can guarantee that all the air in the room will be filtered. Some air purifiers have problems taking the air from the corners of the room. A considerable advantage of Honeywell 50250-S is its design. Thanks to the design, it can suck and release fresh air from all sides, and because of that, this air purifier is having high scores at air circulation.

Cool Design

Not only design is helping this air purifier to be most effective and able to suck the air from corners, but this oval design makes this air purifier also attractive. People can mistake this air purifier for a trash can. The only difference from a trash can and Honeywell 50250-S is that the smell coming from Honeywell air purifier is pleasant and fresh.

Difference Between 50250-S and 50250-N

There is one of the most crucial differences between those two models, and that is the filtering system. 50250-N is using a permanent filter, which means that the filter in 50250-N is not rated as true HEPA filter because true HEPA filters need to be changed periodically. This difference makes the 50250-S much better model. If you are looking to buy an air purifier for allergies, then you should without a doubt go with S model and avoid permanent filter air purifiers because they are not good enough to remove all allergens from the air.

Built For Large Rooms

A large room air cleaner is a good investment if you have a large room or if you maintain a large bedroom. If you live in a smaller place, you should definitely consider an air purifier for a medium-sized room. If you buy a smaller air purifier, you will save money on the initial purchase but also filter replacement and maintenance costs are lower on air purifiers built for smaller rooms.

For example, in a small room of 80 square feet, this air purifier is capable of changing the air 23 times in one hour. That means that your air will be filtered entirely 23 times in just one hour. That is actually overkilling unless you have a constant source of pollution, then such a high rate is a good thing to have. In a medium-size room of 149 square feet, the air purifier is capable of 12 times complete air filtration in one hour. That is still a reasonable rate and also a bit overkill if the room is not getting polluted by dirty air. Recommended size is a large room of 390 square feet, and in such large room, Honeywell air purifier is capable of removing all air 5 times in one hour. Overall reasonable rates and more than you probably need.

If money is no concern for you, then we can highly recommend using Honeywell 50250-S even in a small room. In a small room, CADR ratings for air purifier will go over the roof, which means that airborne particles will be filtered at a faster rate.

SurroundSeal Technology

Honeywell uses patented technology in this air purifier model. With SurroundSeal technology, air leaks are minimized, which means that all the air is pulled through the air filtration system. This is a very useful technology because motors that suck air will not waste energy on sucking the air that is not filtered. 

Indicators and options

On the air purifier, you have an option to choose different fan speed. There are three speeds which you can select. Besides the fan speed options, you can monitor lights that indicate when you should check the filter. There are two lights, one for True HEPA filter and other for pre-filter. 

Replacement Filters

Maintenance of Honeywell 50250-S is not expensive. You should make sure you are buying the original filter that fits your air purifier model. You can purchase different filter packages. You can choose between one HEPA filter and one to four carbon wraps. The more carbon wraps you buy, the longer will your activated carbon filter stay at maximum capacity of removing bad odors.

Replacing new filter is not hard, and even people who never did filter replacement before can replace it. All you need to do is open air purifier, remove the top and take the old filter. Then after you remove old dirty filter place the new filter inside and all you need to do is close the air purifier. Filter replacements on modern true HEPA filter systems are simplified because filter replacement is essential and everyone needs to change the filter sooner or later. Honeywell says to replace the filter every 5 years, but that is too long, and it is highly recommended to change filters every 6 months especially if you are using air purifier a lot and if the room is contaminated with lots of airborne particles.
