Sharp has outdone itself with this product. They’ve managed to incorporate everything one would want in an air purifier and humidifier combo in a lovely, well-designed package. 

With a range of 341 square feet, the laboratory certified product has a clean air delivery rate (CADR) that’s astonishing. Measured in cubic feet per minute, the KC860U has a CADR value of 231 for dust, 220 for smoke, and 245 for pollen. 

Sharp’s patented Plasmacluster Ion Technology enables this filtration performance. This removes microscopic pollutants and toxins that similar products can’t by mimicking nature’s cleansing methods: creating negative and positive ions from water vapor in the air. 

This technology is so safe that it’s ARB Certified. It produces less than 0.001 parts per notation of ozone, which is the lowest standard set by government monitoring authorities like the FDA. 

The KC860U is equipped with an intuitive user interface, which allows ease of use and displays essential information such as the humidity or the level of toxins in your room. Sensors have been integrated into the product to enable automatic adjustments to fan speeds. 

All these features are complemented by its humidifying capability, making this product one of a kind. With 99.97 percent of toxic particles removed and a five-year warranty, there’s hardly a better product on the market. 


  • Very effective air purifier. 
  • Quiet.
  • Little to no ozone is produced. 
  • Well-designed.

Mold spores, dust mites, pollen, and pet dander are removed while humidifying the air. The product is made for spaces of up to 860 square feet. This makes it ideal for large open areas in office buildings and homes.

The product comes with an Airwasher feature that hydrates your skin. This is very useful for workers who spend long hours indoors and experience skin dehydration throughout the day.

3. BONECO – Air Washer W200 Hybrid Humidifier & Air Purifier — Easiest to Clean

As an Amazon Associate I earn from qualifying purchases. Last update on 2024-07-13 at 09:11

The one thing people who own air purifier and humidifier combos distastefully experience is having to clean and wash the filters and other parts of the product. Boneco has provided some convenience to owners by ensuring the Airwasher W200 has parts that are easy to disassemble and dishwasher safe. 

The mechanism used for filtration includes an evaporator mat that rotates in water and adds moisture to the air. This water then acts as a natural filter by ridding the air of pollutants and toxins. Because of this method of filtration, the product is suitably named an “air washer.” 

Two operating modes have been configured in the product. Day Mode allows for maximum output, which unsurprisingly makes the Air Washer louder than the other mode. The Night Mode is a less intensive, but still effective, operation which enables it to be very quiet, providing a more conducive environment for sleeping. 


  • Easy to clean.
  • Configured with convenient operating modes. 
  • Whisper-quiet at night.
  • The light emitted is dim, so there’s no disturbance.


  • Other products can perform at maximum output with little noise.
  • Not effective in large spaces.

4. Opolar Evaporative Humidifier with Wick Filter — Best Budget Air Purifier and Humidifier Combo

No products found.

An air purifier and humidifier combo isn’t cheap. This isn’t great news for those who live on a budget but understand the fundamental importance of having such a product in their house. Health and safety precautions shouldn’t have an enormous price tag attached to them, and Opolar has made sure of that. 

The Evaporative Humidifier does everything one would want from a product of this sort but at a fraction of the price. It functions on an evaporative principle that converts water vapor into nano-water molecules. 

These molecules moisten the air (like the Boneco Airwasher) and purify it. They’re evenly distributed through a 360-degree air outlet, helping you avoid coughs, dry skin, and allergies.

It also comes with a 0.8-gallon water tank that ensures the air purifier and humidifier combo covers an area of up to 400 square feet, so homes and small offices can make use of it.

The filtration system is designed in a honeycomb structure. The integrated filter removes mineral deposits, dust, and other toxins or pollutants to release clean and healthy air in the room.

Unlike traditional or “normal” cool mist humidifiers, Opolar has made sure there isn’t water leakage or white dust on the floor. This attention to detail is impressive, considering the price.


  • Relatively cheap. 
  • Made with high quality. 
  • Nearly all features you’d expect are included. 
  • 400 square feet range.
  • No water leakage or mist.


  • Not as effective as other humidifiers.
  • No automatic shutoff.

This versatile air purifier protects you and your family from a variety of pollutants. These include mold, viruses, dust mites, pollen, and smoke. It’s common for children to have allergic reactions to such pollutants, and removing them from your house provides a healthy environment for them.

These could be for daily use, creating a pleasant environment that’s conducive to deep restful sleep, or for providing a safe and serene atmosphere for a baby.

As an Amazon Associate I earn from qualifying purchases. Last update on 2024-07-13 at 09:11

Many air purification systems claim to remove unpleasant odors from your room, but very few actually do. The Brondell O2+ Revive is one of those few. It ensures your room — that can be sized up to 627 square feet — is a delight to be in by adding moisture to filtered air. 

More importantly, for parents, the purification function removes potential allergens from the air. The dual True HEPA filters remove 99.97 percent of bacteria faster than comparably sized products. This enables the device to refresh the air three times per hour. 

In addition, the Brondell O2+ Revive produces even and consistent humidification, keeping your rooms cool during the hotter months. Cooling is carried out in the form of hygienic mist and hydrated air that are dispersed by the product at regular intervals.

  • Odor removal. 
  • Air refreshed three times per hour. 
  • Asthma and allergy-friendly. 
  • Removes 99.7 percent of bacteria. 


  • Awkward to fill.
  • Heavy and bulky to move around.

What to Look for When Buying an Air Purifier and Humidifier Combo

Coverage Area 

The area the air purifier and humidifier combo covers is crucial because air molecules work on the principle of diffusion. So if a room is so large that the product you buy can’t cleanse all the air in it then, toxic molecules will concentrate themselves in little pockets of space while others move towards the humidifier. 

To ensure your entire room is covered, purchase a product with great coverage or purchase two products to be used in the same room. 

Noise Level

The less noise, the better. Sound is measured in decibels. A whisper has a value of about 16 decibels, while a normal conversation has 60 decibels. Anything more than 50 decibels shouldn’t be tolerated for an air purifier and humidifier combo. But more than that, you should check for the noise level when it’s in its “quiet mode.” 

Around 40 decibels may be a very quiet conversation, but this noise level isn’t conducive to sleep. For more efficient sleep you need a product that produces less than 15 decibels in its quiet mode. 

Air Filtration Efficiency 

Air filtration and purification is the reason you buy a product like this. The CADR values of the product provide a comprehensive starting point on the potency of the product. But for a detailed description of filtration efficiency — measured in percentages — you must trust the manufacturer is honest with their claims. This is why you should only buy from reputable brands, 

If a product claims to remove at least 97 percent of toxins in the air then it’s a good product. Because of the high infectious rate of airborne diseases, a filtration system that allows even 5 percent of toxins to remain in the air is simply not good enough. 


Think about running time. Some purifier humidifier combos have large water tanks and can operate for days without the need to fill it, while others last only a few hours. The best products are obviously those which can perform efficiently for a longer time on a single fill, as you won’t always be available.

Cleaning anything is a hassle. Cleaning components from an air purifier can be a laborious task. Ensuring your air purifier is dishwasher safe will save you a lot of time in the future. 

Filters and other components need to be replaced on a regular basis. How long each component or filter lasts is what determines the operating costs. If you need to replace components after short term use, you’re better off investing in a more expensive product. 


What Price Range Is a Good Air Purifier and Humidifier Combo?

As a safe bet, you should be prepared to spend at least 100 dollars.

Should I Buy a Second-Hand Product?

No. Avoid this. It’s difficult to determine filtration efficiency when a product isn’t brand new.

Which Rooms Should I Have My Air Purifier and Humidifier in If I Only Have One? 

That depends on your family. If you have a toddler or infant whose immune system isn’t fully developed, then the room which they spend the most time in. 


This comprehensive guide has hopefully shed light on the importance of an air purifier and humidifier combo. The Sharp KC860U is the best air purifier and humidifier combo on our list. But that doesn’t mean it’s the best product for everyone. 

Other people may prefer cheaper options or products that offer something different, like a broader range. For example, office users would find the Venta LW45 to be a suitable alternative, while parents with new-borns would love the BONECO H300

Whatever your inclinations lead you to, ensure you protect both you and your family by purchasing one of these products.
