GermGuardian AC4825 3-in-1 Air Purifier

According to EPA (Environmental Protection Agency), indoor levels of pollutants may be 2 to 5 times higher than outdoor pollutant levels. What this means is the importance of indoor air quality cannot be underestimated. For many of us who spend the majority of our day being indoors, it makes perfect sense to buy a quality air purifier that features multiple levels of cleaning. In this article, we will discuss some of the pros and cons of the GermGuardian AC4825, a 3-in-1 air cleaning system that is designed to capture allergens, kill airborne viruses and bacteria, and destroy mold and odors.

The GermGuardian AC4825 offers True HEPA air filtration system to capture airborne allergens. Filters that meet the HEPA standard remove 99.97 percent of particles down to 0.3 micrometers (µm) in size. This is definitely beneficial for asthma and allergy sufferers since pet dander, dust mite allergen, pollen, plant spores, fungi, and mold spores are the most common cause of indoor allergy and asthma attacks. The average size of thoese common indoor airborne particles ranges from about 100 microns down to about 0.3 microns.

The AC4825 also uses an activated carbon as part of its filtration system to reduce household odors and gases that allergic people find offensive. As mentioned before, HEPA filters have the ability to remove the majority of air contaminants down to the microscopic level. However, smoke particles and odors from pets and cooking are too small to be trapped by them. Tobacco smoke particles, for instance, are typically smaller than 1 microns. Carbon filters have tiny pores that allow for the adsorption of odorous substances.

Different filtration systems target different pollutants. To improve indoor air quality, UV-C light is used in conjunction with HEPA filtration and activated carbon. Waves shorter
than violet are called ultraviolet. UV-C is part of the ultraviolet light spectrum. It has been known that short-wavelength ultraviolet radiation (UV-C) creates a deadly effect on microorganisms by altering their genetic structure. It is important to note however that the effectiveness of UV light on microorganisms depends on several factors such as the power of the UV source and exposure time.

The 22-Inch tower air purifier also comes equipped with change filter indicator. There is a green power light that will turn red and flash continuously to tell you that it is time to replace the filter. The replacement filter b for the AC4800 model series from GermGuardian is available on Amazon for around $30. The combination filter includes pre filter and true hepa filter as well as a charcoal filter that helps reduce household odors. On the front of air cleaner is a blue light that will begin to flash continuously when it is time for UV-C bulb replacement.

This air cleaner has a CADR (Clean Air Delivery Rate) of 100+ for tobacco smoke. The performance can be expected during the first 72 hours of use. According to GermGuardian, it is suggested for use in a single, closed room measuring up to 155 square feet. If your room size is smaller, it will simply clean the air faster. Just keep in mind that the calculation assumes an 8-foot ceiling. If your ceiling is taller than 8 feet, consider to get the one which is rated for a larger room.

PROS:

  • Easy to set up
  • Durable even with daily use
  • Does a great job of purifying the air

CONS:

  • Can be noisy when set on high

Key Features:

  • Captures 99.97 percent of dust and allergens
  • Captures particles as small as .3 microns
  • UV-C light technology that works with Titanium Dioxide

  • Brand: Guardian Technologies

Bissell Air220 2609A

The Bissell air220 is intuitive and unobtrusive. It has a single power button and a fan speed dial with five fan speeds and an “Auto” mode. It has a tiny display panel that shows the fan setting, and three different LEDs give you general information about the ambient air quality. The air220 is designed to fade into the background, rather than draw the eye, a fact that will please those who don’t want a big obvious air purifier to break up the visual appeal of a room.

During at-home testing, users found that the air220 did a solid job of getting rid of pot smoke, but it struggled a bit more to remove the smell of incense. In our lab, it performed similarly, where it wasn’t quite able to dispel the smell of peppermint from our sealed test room after running for four hours.

The fastest fan setting isn’t too loud, and it automatically switches over to night mode and turns off the machine lights when it senses low ambient light levels. The Bissell has a nice cord storage system, but the too-shallow handle means that you have to hold it with two hands when moving it around. If you prefer the set-it-and-forget-it approach to air purifying, then you’ll appreciate the Bissell air220.

PROS:

  • Easy to use
  • Relatively quiet operation

CONS:

  • Inadequate handle

Key Features:

  • Offers 3-stage air purification
  • The fabric, pre-filter is washable
  • Easy to operate controls

Specification:

  • Brand: Olfi
  • Model: one.five Black Edition(2nd gen)
  • Weight: 2 pounds

Honeywell HPA300

The HPA300 is the flagship model in Honeywell’s line of HEPA air purifiers. It performs excellently in large spaces and homes, for up to 465 square feet. The HPA300 also uses easy-to-maintain filters. For this price, you can expect fantastic air-purifying performance-per-square-feet at a bargain.

PROS:

  • Sleek design
  • Easy setup and operation
  • Quiet operation

CONS:

  • No air quality sensor

Key Features:

  • 4 air cleaning levels
  • Filters and circulates Room Air 5X per hou

Specification:

  • Brand: Honeywell
  • Model: HPA300
  • Weight: 21 pounds

Austin Air Healthmate

We would marry the HealthMate if it was legal. It’s the best rated air purifier with respect to performance.

The HealthMate’s filtration process is top-notch, nearly industrial-grade. It’s a four-stage, mechanical purification system that first stops large particles like those from pet dander and dust, then medium-sized particles like pollen before passing air through the fifteen-pound, activated carbon and zeolite filter (it’s a beast), and then finally removing the the smallest contaminants with its HEPA filter. Through the mechanical filters and stage filtration, you can finally rid your living space of dust particles and pollen with this appliance. This purifier’s powerful air filtration will catch particles of all sizes before they get the chance to contaminate either a smaller room or large space and trigger health issues such as asthma or allergy symptoms.

While Austin Air claims this unit is capable of handling interior spaces as large as 1500 sq ft, we recommend spaces no larger than 341 sq ft based on the smoke CADR rating of 220.

From a controls perspective, this is about as simple as it gets. Much like the best air conditioners, it is easy to use. The unit features a four position, three speed control switch on its front cover, and the filter can be replaced by removing the bottom plate with four screws, and then simply pulling the pre-filter and primary filter assembly out of the HealthMate. Also, the purifier sits on a set of swivel caster wheels which helps a lot when moving the not so light 45 pound air cleaner.

PROS:

  • Filters dont need to be replaced often
  • Has decent area coverage
  • 4 stage filter

CONS:

  • No filter change indicator

Key Features:

  • 360° Progressive Filtering Intake System
  • Provides cleaner, healthier air guaranteed
  • Casters provided for easy movement around the house
  • Baked-on powder coat finish
  • Available in multiple colors to match any room

Specification:

  • Brand: Austin Air Systems
  • Model: B400A1
  • Weight: 45 pounds

Blueair Blue Pure 411+

The Blue Pure 411+ is a way for people to explore the possibility of cleaner air without spending a lot of money. Between its small size and its futuristic, cylindrical design, it’s easy to fit into any home. If you want to make the device less noticeable, you can use the optional black fabric pre-filter, which easily slips over the outside of the unit. You can switch between the three fan speeds by tapping the central button multiple times.

When our tester took this air purifier home, he put it through its paces by subjecting it to sweaty workout clothes and the smell of cooked onions, both of which the Blue Pure 411+ handled pretty well. In our lab smell test, it had a tougher time removing cigarette smoke from our airtight testing room. We also noticed that, when we tried the Blue Pure 411+ in another room after the cigarette smoke test, the clean air that it vented out had a smoky odor; if you do need to remove more intense smells or contaminants, be sure to let it air out a bit afterwards before using it again.

The fastest fan setting is loud, but not as loud as some of the larger air purifiers we tested. While the Blue Pure 411+ lacks a handle, it’s light enough that you can simply pick it up and move it as needed. If you want a basic device that looks more expensive than its price tag, then check out the Blue Pure 411+.

PROS:

  • Sleek aesthetics
  • Easy to move

CONS:

  • Retained smoky smell after running in room with cigarette smoke

Key Features:

  • Filter replacement indicator
  • Speed control options
  • Integrated air sensors

Specification:

  • Brand lueair
  • Model: 411PACF105372
  • Weight: 7.98 pounds

 How do I buy the right air purifier?

Best air purifiers – What can air purifiers do?

Air purifiers use a fan to pull in dirty air at one end, remove pollutants, and output clean air at the other end. The exact pollutants that can be cleaned depend on the technology used. All of the air purifiers we’ve tested here use a HEPA filter, which will capture a minimum of 99.97% of airborne particles 0.3µm in size. Also known as particulate matter, these particles can penetrate your lungs causing respiratory problems, particularly in allergy sufferers.

Particulate matter sources include dust, with cleaning likely to disturb dust and throw it into the air, pet hair and dander, smoke and pollens. HEPA filters are no good where dust has settled, since the filters can remove only airborne particles. In other words, you still need to clean effectively. HEPA filters also have a lifespan, after which they’ll need to be replaced. The exact timing will depend on the air purifier and how dirty your air is, but expect to buy a new filter between three months and 12 months of operation.

Volatile Organic Compounds (VOCs) are harmful chemicals that are often found in cleaning products, paints, and some beauty products. VOCs are also found in some manufactured products, such as synthetic carpets and old furniture. Most air purifiers can’t touch these pollutants; those that can, can’t filter all VOCs.

Instead, you’re better off with an air monitor, such as the excellent Foobot, to monitor your home to see what’s giving off VOCs. Where possible, switch to less harmful products. Some models of air purifier also have an ionisation option. These use negative ions, which causes particles to stick to surfaces – such as wall or floor. Ionisation has been shown to reduce the risk of some viruses. Ionisation on its own isn’t particularly effective, so always combine with a proper air purifier.

Best air purifiers – What else should I look for?

All air purifiers use a fan of some description, so look for one that runs quietly enough for your intended use. We measure sound at maximum and minimum settings to help you choose. An automatic mode that ramps up the fan when the purifier detects dirty air is useful, as you can leave the purifier to do its job. You need to match the air purifier you buy to the size of room or space that you want to keep clean. Purifiers are rated by the square metre, so buy one that’s big enough.

Finally, you can look out for the Clean Air Delivery Rate (CADR), which tells you how effective the purifier is at different types of allergen, compared to introducing clean air. For example, an air purifier with a CADR score of 190 for dust particles is as effective as adding 190 cubic feet of clean air per minute. In short, the higher the CADR rating for each type, the better. And, CADR scores are comparable across all products, helping you make the right choice.

CADR has three main ratings to help you decide: smoke uses very small particle sizes of 0.09 to 1µm; dust has particle sizes of 0.5 to 3µm; and pollen uses particle sizes of 5 to 11µm. It’s best to choose your air purifier based on how effective it is at the pollutant you want to remove. Hayfever sufferers, for example, should choose an air purifier that’s efficient for pollen removal.

Finally, since air purifiers come in different sizes, the CADR rating should equal (or exceed) 2/3 of your room size in square feet. A 135-sqft room would need CADR ratings of 90 or above, for example.
