In this post, you would find Honeywell Airgenius 5 reviews, Honeywell Airgenius 4 review, Honeywell Airgenius 3 review, and comparisons between them. HEPA-filtered air cleaners are often criticized for their noisiness and extra costs for recurred filters. As an improved model, Honeywell’s “FHD”does not have the same problem, and is more popular in the market.In 2012 Honeywell released three new FHD air purifier models, the Air Genius series: Honeywell AirGenius 3 (HFD-300), costs between $130 – $180; Honeywell AirGenius 4 (HFD-310), costs around $150 – $200, and AirGenius 5 (Honeywell AirGenius 5 reviews here) (HFD – 320), price around $200.They all look modern, with contemporary sleek tower design and a classic color of black (AirGenius 4, 5) or white (AirGenius 3). Put them into any room, and you’ll find them quite appealing.They are energy star rated, a good character for air-purifier, as most of them must be kept on for 24/7. Their filters are permanent washable, this also saves money in the long run.

All of them can filter up to 99.9% of harmful particles in the air, not as good as HEPA-filter, but are enough for most customers, who only have seasonal pollen allergies. For those who have chemicals or advanced allergies HEPA-filter might be a better choice.They also have an oscillating feature that “helps to disperse fresher and cleaner air throughout the room”, just like a fan. usb water air purifierBut most people do not need a fan, they just need air-purifier, so I would advise you to turn it off, because this function may also cause a little bit noise in your room.air cleaner pet odorAlthough they all belong to the same product line and have many similarities, the price difference exists for good reason.best brass cleaning rodAirGenius 5 have a touch sensitive control panel, what 3 and 4 don’t have, and it is considered “smarter”.

It has 5 fan speeds: Sleep, Germ, General, Allergen, and Max. and HFD – 320 has a auto-off function with 6 intervals, from two to twelve hours.AirGenius 4 have four fan speeds, and four intervals for auto-off timer. AirGenius 3 have only three fan speeds and no time controls.Theoretically are AirGenius 4 and 5 certified for large rooms up to 250 square feet, but if you are lazy and don’t want to clean your electronic filter at least once a month, it’s better to limit the area to about 170 square feet.The same applies to AirGenius 3, recommended room size for 3 is 160 square feet instead of the certified 225 square feet.CADR rates for AirGenius four and five are the same: rating for dust is 160, pollen 170, smoke 161. Performance of AirGenius three is not so good, with 150 for dust, 160 for pollen and 146 for smoke. Most experts would not recommend air purifiers that are under150 CADR ratings, so the AirGenius series are acceptable, but just borderline.Manufacturer of the HFD grid suggests it should be washed four times a year, but as I’ve mentioned, better is once a month, and you should also clean the entire air purifier simultaneously.

Though compared with earlier designs, some of which needed nearly daily cleaning, this is a huge improvement. By washing you should soak the grid for 2-3 minutes, longer than that is also not acceptable. And what’s important, it can’t be put in a dishwasher. Before you replacing it inside the AirGenius again, you have to make sure it’s completely dry.Warranty for AirGenius is pretty long, a five-year warranty is enough for most buyers. But be careful, normal wear and tear, and filters are not included in this warranty. The company also demands proof purchase, as well as 10 extra dollars for return shipping.It’s an acceptable model, with attractive appearance and stylish design. It’s light-weighted and easy to carry around. When you turn the oscillation function off, it’s quiet and not noisy. It suits normal people without allergens or those who have light allergic reactions to mold and pollens. It can make them feel better and refreshed.The price is a little bit high, but the lifespan for this machine is long, a 5-year warranty is also a plus.

You don’t have to pay a lot of money for its maintenance.But for those who have severer allergic problems and people who smokes is this model not very advisable. It’s simply not strong enough to help you. You could also find some smoke air purifiers here.Dyson really hates dirt, to the point that it's now come up with a new bladeless fan that can also filter out ultrafine airborne particles -- including viruses, bacteria and pollens -- that are as tiny as 0.1 microns. The aptly-named Pure Cool (AM11) closely resembles Dyson's other fan towers, with the notable difference being the cylindrical glass HEPA filter around the base. After 450 prototypes, the company claims that this filter removes 99.95 percent of ultrafine particles, and it's good for up to 4,382 hours or about six months of continuous use. In other words, if you use the Pure Cool for 12 hours each day, then you'll only need to replace the filter after a year. Of course, it's hard to say whether it'll last just as long in smoggy Beijing, which is where Dyson cleverly chose to do the global launch for the Pure Cool.

Gallery: Dyson Pure Cool hands-on | I've tried the Pure Cool for a night so far, and it really is quiet at mid-speed while also oscillating, so it didn't affect my sleep. If needed, you can set a sleep timer for anywhere between 15 minutes to nine hours, and this can be adjusted using the remote control that rests on the fan's magnetic top. As to the effectiveness of the HEPA filter (which isn't hard to remove), this will require a much longer trial to tell, so we'll just have to take Dyson's word for it.It's a given that the Pure Cool will be gradually rolled out across the globe, but for your reference, it'll be available in Hong Kong this May from April 17th for HK$5,580 or about US$720. If you prefer the cheaper yen, then it'll also be available for ¥69,984 (tax included) or about US$580 in Japan -- a country where Dyson has a habit of debuting its latest goodies. But yes, it's still pricey. The box of my fan states it includes a fused safety plug. what does this mean?
