Introduction
If nasty odors are something that causes you discomfort in your home, then you should consider getting an air purifier for your home. Fixing that problem should drastically improve the quality of life in your home and you will not need to worry about embarrassing yourself when someone comes to visit your place. Winix air purifiers might just be the solution you need when you need to freshen up your house.
There are several models that we can advise you to chose from: Winix 5500-2, Winix 5300-2, Winix NK105, and Winix U450. In this review, we are going to explain what each of these models excels at and it will probably give you a rough idea which one is best suited for your needs.
What do they have in common?
We chose to review this group of devices since we feel that they are the best when it comes to getting rid of nasty smells.
All of the models are capable of getting rid of 99.97% of particles from the air. Those include dust mites, pet dander, pollen and other allergens which are all as small as 0.3 microns.
All of the models mentioned also have a carbon filter which is paramount when it comes to getting rid of smells.

You need to be prepared to clean that carbon filter and that can be a messy and smelly experience since it has collected all of the foul particles. Keep in mind that while carbon filters are washable, others need to be periodically replaced and it can cost up to a $100.00 All 4 models also use the PlasmaWave technology.
The producer advertises the fact that these models are quiet so it is safe to put them in your bedroom and leave them to work even on the higher settings during the night while you are sleeping. That is where the similarities between the products end and we will now discuss where they differ and what are the benefits and drawbacks of each other.
