GermGuardian AC4825– True HEPA filter for smoke under $100
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.
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.
True 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
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.
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.
Blueair 503– expensive but powerful for smoke
Let’s be clear: though the hefty price tag is not for most people, Blueair 503 is still the most powerful air purifier, rated at (CADR) 375.
When filtering an area of 500 sq. feet in size and delivering an ACH rating of 4.8 changes per hour for smoke, pollen and dust, it is far more efficient than other models on the market.
The Blueair is also a world-renowned brand for air filters. The sleek Swedish design and the silent filtration technology makes this brand stand out amongst many other top-level brands.
This is one of the highlights of the shark, look at the basic filter, the dirty seems to stand for how well they work. fortunately, these filters are washable. the basic filter is a foam filter and post air return filter is a HEPA filter inside of an egg crate style frame. That is the grille you see on the front, easy to disassemble
One of the outstanding features of this air purifier is the silent operation of this model. It attributes 4 different fan speeds that include turbo and sleep modes. Even when the air purifier is set on high power, it produces almost negligible sound. This device is great for bedrooms.
Winix PlasmaWave 5300-low budget choice for allergies and asthma
The Plasmawave 5300 is a low-budget choice that offers clean air and a great price.
It is a slight downgrade of Winix’s pricier 5000 series, retaining all but the peripheral features of the latter model. The 5300 is suitable for 350 square feet of room. With True-HEPA filtration, and a combination of Plasmawave and odor control carbon pre-filtration technology, it eliminates 99.97% of particles and indoor odors.
The automatic mode adjusts the operating speed automatically with a special sensor to detect the purity of the air. Plasmawave 5300 has a one-year limited warranty.
Winix WAC9500 is a no-frills affair, but offers outstanding performance in its core function. Many customer reviews mention that the 5300 is undoubtedly the best air purifier in its price bracket.
Rabbit Air BioGS 2.0 – smooth design and user-friendly features
The award-winning SPA-625A is a stylishly designed air purifier that is user-friendly with comprehensive functionality. It features a beautifully clean design that doesn’t scream, “Hey, I’m an air purifier!”. The SPA625A has a hard steel exterior that gives it remarkable durability.

The filters are highly durable, lasting up to 3 years when operated 12 hours daily. Additionally, the pre-filter is permanent and washable.
Quiet / Sleep mode/childproof
The Brushless Direct Current Motor (BLDC) makes it extremely quiet, producing almost no sound at the lowest speed.
The filters are highly durable, lasting up to 3 years when operated 12 hours daily. Additionally, the pre-filter is permanent and washable.
The screen will automatically darken at night, so it won’t interfere with sleep.

Reviews from customers are mostly positive, with many users praising the SPA-625A’s effectiveness, energy efficiency, curvy design and quiet running. The few negative remarks mainly have to do with the fact that it is a bit pricy, though they also mention that this air purifier is worth the extra few bucks.
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.
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 sneeze，no 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.
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.
Best Air Purifier for dust – Honeywell 5025
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.
Best Air Purifier For bedroom and office –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 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.
What 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.
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.
What 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.
