They are made of fiberglass which depending on the design, could be thicker than some others and are good at the interception of molecules.

Special features: compact, item weight; 6 pounds, dual positioning.

This type of air purifier takes a completely different trajectory to the previous two reviewed so far, being nothing in looks when compared with the tower type.

The unit is pretty small and compact, and can easily be confused with a portable speaker, though it is heavier with its 6 pounds weight.

The dual positioning design ensures that the unit can be placed easily anywhere around the home in a horizontal or vertical manner, being used as a table or desktop.

It is designed with three fan speeds that can be toggled by the presence of a control knob at the top side and depending on the contamination level in the atmosphere; you should select the most suitable. Although it is built to be quiet, and it actually is while running, at higher fan speeds, there is much more noise emission that the lower stages.

It is able to serve really small room sizes though which is seen as a major letdown, with a capacity good enough to cover only up to 100sqft. The device comes with a HEPA filter actually, which does a good job in the purification of the air, though it lacks the charcoal, pre-filter or UV light found in some others.

Instead, it makes use of a baking soda, carbon, and zeolite combined filter for odor control. There is an option of an ionizer too, which is taken, further adds a good level of further purification to the already existing processes in the unit.

With purchasing this unit, comes a three years limited manufacturer’s warranty, which is a good covering, and encouragement for customers looking to take the gamble. When used with the proper recommendations, this air purifier would actually do a good job, and as soon as the filter condition becomes unhealthy, an indicator light pops up to alert the user and hence keep your filtration clean.

There’s also a filter replacement indicator for when the filters require maintenance.

The unit is designed to serve room sizes up to 160sqft, which isn’t so impressive, and why we recommend you look further if it’s not such small space. Like the Holmes type, it comes with the dual position design, meaning it can be placed both horizontally and vertically depending on the availability of space or your preference.

  • Filter replacement frequency and efficiency:

The filters in a unit determines the degree to which it can effectively purify the air in the home, and due to the fact that air is always forced through it, most times it needs to be cleaned or changed regularly. For units with expensive filters, eventually they can become more costly than the price of the product itself.

  • Air purifying filters and stages:

Also the quality of filter matters, especially for people with allergies and asthma, therefore for maximum productivity, it is important the unit you purchase has at least a true HEPA filter. Other layers of filtrations like the carbon, pre-filter, and ionizers would also be beneficial.
