These purifiers work through a three stage filtration process which includes a washable pre-filter, a True HEPA filter, and an active carbon filter. The filters are placed in a 3-in-1 combined unit and in a pop-up filter cartridge for easier replacement with their grill designed for easy cleaning. All models come with filter change indicators and in case if there is a need. Also, customers can order a model with an ionizer which works better in freshening indoor air. The ionizer can also cover an area of up to 180 sq ft through their two way filtration system consisting of a carbon pre-filter and a HEPA filter.
However, its air purifying power leaves a lot to desire. Covering up to a maximum of only 200 sq ft, Delonghi Fresh Zone models listed a low circulated air delivery rate of only 70 despite its three stage filtration system and four speed fan. Small models such as the FZ DAP 70 are equipped with three speed fans but can only cover an area of 110 sq ft. However it’s its lack of performance is compensated by being one of the lightest air purifiers around, weighing at only eight pounds. Models can be placed vertically, horizontally or mounted on the walls due to its light weight, and rubber feet are added for more stability.
Biozone Air Purification Technologies
Biozone air cleaners merge four advanced engineered electronics methods in their purifiers to clean the indoor environment.
- Photolic ozonation (an euphemism for chemically active oxygen atoms) is applicable to eliminate odors, make harmless certain gases, and destroy live contaminants found in the air and also on top of many surfaces. In order to control the accumulation of ozone, Biozone uses SafeZone, a fail-safe method which detects ozone levels in its surrounding environment and automatically reduces its production of ozone to safer levels. However, this claim has not been scientifically tested for its effectiveness.
- Next, certain concentrated ultraviolet light is also used to kill micro organisms such as bacteria and viruses. Ultra-violet light, widely used in sanitizing scientific equipments and medical rooms helps destroy excessive ozone molecules, keeps the two systems in balance.
- In addition to that, purifying hydroxyls which can be formed from air components, aids further destruction of contaminants. The combination of ultraviolet light and purifying plasma can clean air and surfaces up to 2000 times faster than ozone alone and compared to just ultraviolet light, 180 times faster.
- Finally, the production of negative ions which attracts solid particles such as dust and pollen and even soot, helps to clear them from the environment. The Biozone air purifier then blows the purified air back into the room, carrying purifying agents to clean the air of stubborn contaminants and unpleasant odors.
All Bionaire air cleaners feature an independent ionizer which can be turned on or off regardless of the mode the cleaner is on. The ionizer releases negative ions into the air to join staticly with positively charged particles such as smoke, dust or pollen which can then be more easily filtered through the HEPA filters, giving you cleaner, more breathable air. Futhermore, each Bionaire air purifier is equipped with Microban Antimicrobial Product Protection which helps preserve the HEPA filter against odor-causing bacteria and more importantly helps extend the life of your HEPA filter.
For even more features, there is the Galileo HEPA Air Purifier. This model is equipped with a built-in air quality sensor which increases fan speeds in times of need. Apart from that, there are 3 adjustable fan speed settings for easy control. This purifier is also programmable for sleep mode ensuring usage in the bedroom. Built in within is a much appreciated feature known as the dual operational positioning for easier access to their options, without the need to move your purifier. Overall, Bionaire’s air purifiers have been designed with refined style and sophistication: versatile, slim and compact, they blend in with the room instead of sticking out like a sore thumb.
Austin Purifier Models
Austin air cleaner model platforms include the Austin Air HealthMate for wider rooms, Austin Air HealthMate Jr. for smaller rooms, and Austin Allergy Machines or models from the ‘Plus’ platforms which caters for allergy and asthma sufferers. Heavier models such as the HealthMate 400 may weigh up to 45 pounds but they come with wheels which allow for easier moving and also casters for easier positioning. Models from the ‘Jr’ lines are smaller in size; with the lightest HealthMate Hega at a mere 2.5 pounds, allowing easier lifting and for limited spaces.
 Industry Leading Warranty
When using any air purifiers, customers are always advised to clean the pre-filters regularly to extend the life of their HEPA filters, but when it comes to warranties for HEPA filters, no other company in the air purification industry can top the 5-year limited warranty Austin offers. For those people who are sensitive towards the use of chemicals in the air, Austin air purifiers from the ‘Plus’ line comes equipped with permafilt pre-filters and activated carbon and zeolite units, all aimed to help remove airborne chemicals, including dangerous and odorless ammonia and formaldehyde. The lighter weight models also contains the same filter but is made of woven cloth, hence not adding any extra weight to the unit.

The weight of this brand of air purifiers may make portability an issue for some. One of such models is The Eagle 5000, which weighs at 35 pounds and works to clear heavy particles such as smoke and dust from the air. This makes it most ideal for smoky bars, restaurants and bowling alleys. Its 100% filled activated charcoal filter significantly reduces a wide variety of odors from the room atmosphere. The fairly lighter Flair, at 10.6 pounds, is more suited to a home or office environment and covers up to an area of 2200 sq ft. It includes a sanitizing feature for eliminating mold, mildew, bacteria and odors from indoor air. Other features of this model are its low maintenance with no installation required.

Each series is equipped with different combinations of purification power to cater to different usage requirements. The AirWash/AirRhino Systems combine mechanical filtration and activated carbon to help reduce specific particles and provide odor and chemical control. Buyers can customize their industrial air purifiers to be equipped with either a true HEPA filter or a MAC-B activated carbon filter, or a combination of both. The filters are easy to change and easy to handle. Other options for these industrial air purifiers include a germicidal UV lamp, pressure seal and gel seal.
AllerAir air purifiers’ I-6500 series contain HEPA filters which are 12 inches deep and a MAC-B activated carbon filter that can be customized to neutralise 4000 noxious chemicals in the air. Plus, a pre-filter is attached to prolong the life of the HEPA filter. The model is ideal for areas where dust or odor problems persist.
Additionally, buyers seeking industrial air purifiers can also look into the AllerAir 9000 series. These air purifying machines are equipped with welding fume extractors that trap gases and chemicals from welding fumes through its 4 stage filters. On the other hand, the AllerAir 9650 comes with built-in carbon filters and a special tar-trap pre-filter to filter smoke particles.
In areas where volatile organic compound problems are abound, the Allerair 8000 is built with specifically manufactured carbon filters for this purpose.
