  • Different air purifiers are designed to remove different pollutants. Before buying, it is important to determine the main pollutants in your home.
  • Don’t forget about the replacement filter price. Some replacement air filters may cost as much as $96! But some can be cleaned and reused, which can help you save money

Best Air Purifier for Smok

The biggest problem for cigarette and cigar smokers is that they have to smoke outside to keep home a smoke-free area, which is very inconvenient.

To remove smoke, we first need to know what smoke is. Smoke is a combination of particles and gasses, and we need different types of filters to remove it. First, let’s begin with particles.

GermGuardian AC4825– True HEPA filter for smoke under $100

GermGuardian AC4825–

It is ideal in medium-size rooms about 155 ft. sq. and CADR rated 100+, not very high but good enough for a bedroom.

It boasts a 3-in-1 Air Cleaning System with a True HEPA Filter, a UV-C, and Odor Reduction to capture allergens, kill airborne viruses and bacteria, and reduce mold and odors.

Filters

First, a pre-filter and a charcoal filter are often used to capture large particles such as dust and lint, as well as the usual household odors. Then, a True HEPA filter captures 99.97% of airborne particles (some as small as .3 microns in size) such as dust mites, debris, mold spores, plant pollens, and pet dander.

lightTrue HEPA Filter?

True HEPA filters are uncommon. Instead of just saying HEPA, many producers add any number of cute prefixes and suffixes to the HEPA term. Look out for HEPA-type, Micro-HEPA, Ultra-HEPA, HEPA-style or other similar variations. The term True HEPA was created to counteract this foolishness. More about the True HEPA Filter

UV-C light

Finally, UV-C light technology helps kill airborne viruses and bacteria, while titanium dioxide is activated by UV-C light to break down odor molecules caused by cooking, pets, and smoking.

UV lights of a certain wavelength emit ozone. If the light wavelength is below 200 nm, it generates ozone. The good news is ozone converts back to oxygen above 200 nm. The light used in AC4825 and AC5000 both are 253.7 nm, so they emit no ozone.

Conclusion

GermGuardian AC4825 air purifier comes loaded with excellent features. On Amazon, as many as 83% of the users who have provided reviews have given it a rating of 4 and above. The average rating is 4.3 out of 5. In addition, AC4825 is a high-value buy because it costs less than $100.

Pros
  • Three levels of cleaning: pre-filter and charcoal filter, True HEPA filter

  • Running all night extremely quiet

  • Energy efficient , Use less than a lightbulb

IQAir HealthPro Plus – for severe allergy and asthma

Do you sneeze for hours every morning? Are you highly allergic to dust mites? Did you buy expensive bed linen and pillow cases and often change your sheets? But nothing can stop you from allergies in the morning, which is the worst time for many sufferers

If you are suffering from severe allergies and asthma, I recommend this product for use in your bedroom. Even if it’s a bit loud at the high-speed setting.

Often used in hospitals and medical facilities. Most famous for being used in Hong Kong to control the SARS outbreak. And IQAir has been certificated by the American Lung Association as an educational partner.

HyperHEPA filterLonglife

IQAir is rated as the world’s best-performing air purifier for allergies and asthma. Patented HyperHEPA® filtration up to 10x more effective than standard HEPA. Remove the dust mites, pollen, pet dander, pet hair -primary causes for the breathing difficulties suffered by those with asthma and allergies. Imagine the difference virtually allergen-free air can make to your health.

According to the feedback, most of the customers with allergies wake up with clear nostrils. No sneezeno anything

Under normal use (running ten hours a day), the V-5 filter (an active charcoal filter only comes with the plus model) will last about two years. The HEPA lasts about four. It depends on the amount of dust and small particles in your air, but I think you have to replace the pre-filter more frequently. Same goes with odors. If you have odor problems, you may need to replace the active charcoal filter more frequently.

They provide 10 years of limited warranty. My old model was purchased in 2002 and has run 24×7 since then, and I have had no issues for 13 years.

Pros
  • Revolutionary HyperHEPA
  • Great noise control
  • 10 years warranty but you may  never used
Cons
  • replacement hyperHEPA filter is very expensive

 

Best Air Purifier for mold 

Mold (disgusting microscopic fungi) often lives in warm, humid, and dark places. It can expose you and your family to serious health risks.

However, the mold itself does not cause allergies or asthma reactions. Instead, the micro-mold spores (seeds) that float through the air are what cause allergy symptoms such coughs, wheezing, and a stuffy or runny nose.

If your home has a mold problem, the first step should always be to remove the mold. Sometimes people think just buying an air purifier will deal with it.

Austin Air HealthMate Jr.

But do air purifiers eliminate mold?

The air purifier does not kill the mold that has grown on the surface, but it does remove the mold from the air. However, running an air purifier at home can reduce the air’s mold spores and ensure that your breathing air is as clean and healthy as possible.

Air Purifiers Eliminate Mold Spores, But…

Although the air purifier eliminates mold spores, this does not solve any potential mold growth problems. To ensure that your family’s air remains mold-free, use a hygrometer to monitor the humidity levels in your home. After testing the humidity level, a dehumidifier can reduce the humidity and keep it in a range not suitable for mold growth.

Pros
  • Designed to be run 24 hours a day
  • Energy saving certification
  • Give you instant results ,since they can totally clean all the air in a room within minutes
Cons
  • white noise 48db on max power
  • Replacement filter is expensive

 

Best Air Purifier for dust – Honeywell 5025

Honeywell 50250-s

Dust is an unfortunate fact of life. While outside of a highly-regulated clean room we will never be completely free of dust, there are still many ways to help reduce the amount of dust in your indoor environment.

One particularly effective way to reduce household dust is to use an air purifier.

What is Dust Made of?

When dust is settled on a surface, it often looks like uniform gray dirt. But dust is actually tiny particles from many different kinds of surprising sources.

  • The composition of the indoor dust varies between each family and is based on many factors, including how many people and pets are in the home and the outdoor environment. However, for most of us, dust is mainly caused by the formation of particles from the outside.
  • External particles may include pollen, mold spores, and other organic debris. For most people, these are harmless, but those with certain health conditions may be harmed due to exposure or inhalation of environmental pollutants (such as those with allergies and asthma).
  • In addition to contributing to the wide range of dust sources, these different particles are significant in size range. For example, dust mites are insignificant in our eyes, but are actually quite large in dust, ranging from 100-300 microns. Pollen varies from a relatively large range of 1000 microns to less than 10 microns. Other particles that make up the dust may even be less than this. The surface of the powder and pigment from paint can be reduced to 0.1 microns inside, and toxic chemical residues such as cigarette smoke can be in the range of 4 to 0.01 microns.

Why Honeywell 50250 Can Help Reduce Dust

Honeywell is one of the most excellent brands known for their outstanding quality in air purifiers.

This air purifier circulates the air in a room, and when it sucks in the air, it absorbs all the tiny particles that fall in it, including dust.

Air passes easily through the filter, but the possibly harmful particles are trapped in the active carbon. Although this air purifier cannot completely remove the particles, the air cleaner’s external grill functions as a deterrent by capturing large particles and preventing them from entering the unit for pre-filtration.

The large particles located in the unit are rapidly captured during the active carbon, which can also eliminate unwanted odors and extend the service life of the HEPA filter.

Pros
  • The carbon pre-filter helps capture larger particles.
  • The True HEPA filter effectively removes microscopic allergens, starting at 0.3 microns.
  • A long-lasting HEPA filter which should be replaced in 3-5 years.
  • CEDR 250, which is high for bedroom.
Cons
  • a little noisy at high settings but tolerable
  • The blue light probably is annoying at night

 

Best Air Purifier For bedroom and officeCoway AP-1512HH 

Coway AP-1512HH

It doesn’t take a lot of effort to understand why this air purifier has been described as the best one sold on the market for less than $300. You only need to look at one or two of its most outstanding features, which include:

CADR

CADR rated 233 (smoke), a high performance considering its compact size (16 x 18 x 9 inches). It also features a glossy black casing complete with a modern air purifier styling.

lightWhat is CADR? does it matter?

The Clean Air Delivery Rate tells us not only how much air is filtered, but also how well it is being purified. The higher the CADR rating, the more effective the air purifier is against that pollutant.

Low power consumption

Who wouldn’t like to have a low-energy consuming air purifier? At just 15.6-watt consumption on the lowest fan setting, you can be sure the air purifier will go a long way to helping you reduce your energy expenses. To put the watt consumption into perspective, the 15.6-watt consumption figure translates to 2.1 extra watts on what a light bulb normally consumes.

Coverage

It is perfect for your office and very suitable for the home. Remember that it uses an ion generator to filter the air. This means that it is strong enough to cope with the 400 square feet of a standard bedroom.Given its size, you can easily move it around, and the unit is very easy to maintain.

The filter lasts for a long time, and the HEPA filter is designed for one year. But if you keep the pre-filter and charcoal filter washed and clean, the HEPA filter will last even longer than that.

lightWhat Is a HEPA Filter (and why should I care?)

In the air filter world, the HEPA standard has evolved as the go-to “good enough” quality level. Developed originally during WWII by the Atomic Energy Commission’s Manhattan Project to clean radiation out of the air, the design evolved over several years into an affordable, mass-produced paper filter system that could be integrated into purifiers, vacuums and other units for commercial and residential use.

Pros
  • Cmpact size ,16 x 18x 9 inch
  • Certified by the California EPA Air Resources Board as a zero-ozone producer.
  • Electricity consumption of 4.9-77.8 watts, about as much as a lightbulb.
Cons
  • Designed to be used in only one room.
  • A little hard to order the replacement filters.
