True HEPA & Activated carbon filterOur kitchen is poorly ventilated, so cooking odors tend to linger. Will an air purifier eliminate the smells? Some manufacturers of air purifiers claim their machines will remove odors from your home as well as improve the overall air quality there. Hoping to sniff out the truth, we put five room air purifiers to the test. Manufacturers use a range of different technologies to enable their machines to remove odors:• The Whirlpool Whispure AP45030S, $230, highly rated in “Filtering the claims,” uses a thin carbon-fiber mat that also serves as a prefilter to remove large particles.• The Bio-Net EGF Enhanced, a $750 electrostatic precipitator–type purifier, has a small shallow cartridge loaded with carbon granules.

• The IQAir HealthPro Plus, $800, and the Austin Air Systems HealthMate HM-400 (shown), $450, are equipped with large cartridges filled with carbon granules. • The Winix PlasmaWave 5000, $300, combines a carbon filter with “PlasmaWave” technology said to, generate “both positive and negative ions” to create plasma clusters that “instantly neutralize viruses, bacteria, chemical vapors and odors in the air.” humbrol airbrush cleanerOver the course of several days, we ran each of the five machines through its paces in the same sealed chamber we used to test for dust and smoke removal. 3m brake cleaner msds sheetsRead the results of the testing below. air duct cleaning lansing ilThe first step involved filling the chamber with a cooking odor by heating ground cumin in an electric frying and pumping the aroma into the room via a duct.

(There was no air purifier in the room at this point.) Every 15 minutes over the course of one hour, our trained panelists, seated at “sniffing stations,” took a test whiff of the chamber air to determine whether the cumin odor in the room was being reduced. The panelists determined that the odor stayed roughly the same during the one-hour test period. To get the room ready for an air purifier, we ventilated it completely. Next, we placed an air purifier in the middle of the room and turned it on and then repeated the cumin test as described above. We followed the same procedure for each model. Our findings: The Whirlpool, Bio-Net, and Winix air purifiers did not remove the odors and proved to be hardly an improvement over no air purifier at all. The IQAir and Austin Air models proved the most effective, though it took them an hour to eliminate the odor completely. Note that neither of these models was among the top performers in our tests for dust and smoke removal. Refer to our Ratings of room and whole-house air purifiers (available to subscribers) to find the top overall performers.

You’ll need to replace the odor filters on your purifier according to the manufacturer’s recommendation, typically every 3 to 12 months. The cost of replacement odor filters for the models tested range from about $8 for the Whirlpool carbon-fiber mat to about $100 for the IQAir large cartridge. Instead of buying an air purifier to get rid of smells, you might do just as well by opening a window even for just a few minutes.—Ed Perratore Essential information: Read “Tip of the day: How to choose an air purifier” for expert advice on choosing an air purifier.Philips GoPure cleans the air in your stinky carThe Philips GoPure Automotive Clean Air System can purify the air in a car's cabin in about 10 minutes.RoadshowNewsAuto TechPhilips GoPure cleans the air in your stinky carHigh-tech air filtration systems and HEPA filters are becoming standard fare in luxury vehicles these days, but what are you going to do about that funny smell in your 2004 Chevy Aveo? There's only so much that a pine tree air freshener can do.

Perhaps you should check out the newly announced Philips GoPure Automotive Clean Air System.The GoPure was the odd bird in Philips' booth at the Automotive Aftermarket Products Expo (AAPEX) in Las Vegas, which was otherwise filled with the manufacturer's line of automotive lighting products. This portable air filtration system is aimed at motorists with allergies, drivers with small children who may be sensitive to airborne germs and particles, and people who want to remove bad smells from the air in their car.The GoPure takes advantage of a three-stage filtration process that Philips says was developed by its Healthcare division. The first stage is coarse prefilter that captures hair and large airborn particles. The next stage is a HEPA filter that captures fine particulates, such as dust and pollen, and airborne bacteria. The final stage consists of three HESA filters that Philips claims will reduce bad odors such as cigarette smoke. The GoPure circulates air through its filtration system with a two-speed fan.

Philips claims that the GoPure can clean the air in a car's cabin in about 10 minutes when set to its high-speed "boost" mode.The demonstration unit on display at AAPEX 2011 sat on the dashboard of a 2012 Fiat 500 and was held in place with a suction cup--a great position for showcasing the product, but I wouldn't want to drive around like that. Philips' product shots showcase some better mounting and placement options, such as under a seat, on the rear parcel shelf, and affixed the back of a seat. Wherever it's mounted, the GoPure draws its power from a 12V plug and automatically powers on and off with the vehicle's ignition.Sensors and LED indicators illuminate to communicate the current ambient air quality. Blue is very good; deep purple is good; and light purple is poor. Lights automatically dim at night to minimize glare while driving. There's also a filter replacement indicator to let owners know when to swap the HESA and HEPA filters.The Philips GoPure carries an MSRP of $249.99, but I'm already seeing prices as low as $185 around the Net.
