What experts didn't like
At its current price of around $300, it is very expensive, although its high up-front cost is somewhat mitigated by its extreme energy efficiency in the long run.

However, you need to be careful while filling, cleaning or moving your air washer if you are to avoid water spills.

My only complaint about the Venta Airwasher 2-in-1 Humidifier & Air Purifier LW25 is the blue light produced by the operator panel.

From The Manufacturer

For rooms up to 400 square feet, the Venta LW25 Airwasher humidifies dry room air while simultaneously purifying it by removing dust, pollen, pet dander, and other airborne pollutants down to 0.3 microns in size. The Venta Airwasher is both a filter-free evaporative humidifier and filter-free air purifier, all in one lightweight unit. Additionally, Venta Airwashers do not produce the white dust common with other humidifiers due to the fact that we use Cold Evaporation technology. By implementing the principle of humidifying and purifying air for homes and offices without using filters, the Venta Airwasher is hygienic, simple to use and easy to clean. Using a Venta Airwasher will help to reduce common cold symptoms caused by dry air such as dry skin, chapped lips and sinus congestion. Keep allergies under control against dust mites, animal dander, and pollen. Perfect indoor air quality cleansed by a Venta Airwasher helps to improve concentration and reduce headaches. Properly humidified air will also eliminate static electricity and work to preserve wooden furniture and musical instruments. Venta Airwashers offer the consistent performance of high-end German engineering; delivering perfect indoor air quality with both humidified and cleaner air to breathe. This compact 2-gallon humidifier is powerful enough to work with indoor spaces of up to 400 square feet, perfect for a living room or master bedroom, and is designed to resist over-humidifying the interior.

An Overview On Home Humidifiers

Anyone who’s struggled through chilly days with cracked lips or burned through jars of lotion during colder months has experienced the effects of dry air. When the air in your home or apartment is too dry, it affects your skin and mucous membranes. This can dry out and irritate your skin, aggravate your sinuses and contribute to coughs and colds. Overly dry air also increases static electricity in your hair and clothes, and it makes cold rooms seem even chillier. Humidifiers reduce these negative effects by adding moisture to the air in your home.

There are several types of humidifiers. Central humidifiers are built into your air conditioning or heating unit, and they generally do a good job of maintaining healthy moisture levels in your air. However, older homes, apartments or homes in very cold, dry climates might need a boost of humidity from portable humidifiers.

Portable humidifiers use different methods to add moisture to cold, dry rooms. Evaporative humidifiers, like the Honeywell Cool Moisture Console Humidifier, are the most common type. They have a reservoir that dispenses water through a wicking filter into a basin, then a fan blows air through the moistened filter to dispense small water droplets throughout the air.

Ultrasonic humidifiers, like the Pure Enrichment MistAire Humidifier, use ultrasonic vibrating diaphragms to force tiny drips of water into your air. They tend to be quieter than other humidifiers.

Both evaporative and ultrasonic humidifiers need to be cleaned regularly to prevent mold, minerals and bacteria from growing in the water basin. However, some higher-end ultrasonic humidifiers, like the Honeywell Germ Free Cool Mist Humidifier, have built-in UV light filters that sanitize your water before it’s exposed to air.

Most modern portable humidifiers use evaporative or ultrasonic technology. Cool mist versions of these humidifiers, like the TaoTronics Humidifier, are also becoming more popular. They emit room-temperature water droplets into the air instead of warm water, making them more suitable for year-round use than steam humidifiers.

After you’ve covered your humidifier basics, there are a few more considerations you’ll want to make before selecting the best unit for your home. 

DYWM Fun Fact

Grumbling about the cost of your portable humidifier? Hey, at least you’re not the Crocker Art Museum in Northern California. After the museum’s $100 million expansion project concluded in 2010, they noticed their humidifier was on the fritz. Paintings, sculptures and other historic works of fine art need to be stored and displayed at specific humidity levels to prevent damage, and a faulty museum humidifier can spell disaster. The people at Crocker fought with their original contractors for years, saying that unit’s repeated failures were putting priceless works at risk. They finally scored a win in 2017, when a judge ruled that the contractors had to pony up $770,000 to replace the unit.

The Home Humidifier Buying Guide

  • Take a look around your home to determine the safest spot for your humidifier. You should make sure to keep it off the floor on a sturdy surface that leaves several inches between the humidifier and your wall and outlets.
  • How much elbow grease are you willing to put into cleaning your humidifier? You’ll need to keep the interior squeaky clean to prevent mineral and mildew buildup. Some options, like the Honeywell Germ Free Cool Mist Humidifier, have UV lights to sanitize your water and dishwasher-safe basins to get into every nook and cranny. However, you’ll have to pay more for these features.
  • Using distilled water instead of tap water can help slow down or prevent mold and mildew growth in your humidifier. It can also help your filter last longer and keep the humidifier other components in better condition.
  • How large is your room or apartment? Some units, like the Pure Enrichment Mist Air Humidifier, are best for small to medium-sized rooms. You might have to buy more than one small unit if you need to increase humidity in multiple rooms. Larger humidifiers can help out in multiple rooms or even your whole house. The Honeywell Cool Moisture Console Humidifier can tackle dry air in rooms up to 2,300 square feet.
  • Who will be using the humidifier? You’ll want a whisper-quiet model, like the TaoTronics Humidifier, for your baby’s nursery. If you’re relying on a humidifier to help alleviate symptoms of asthma or allergies, an ultra-hygienic option like the Honeywell Germ Free Cool Mist Humidifier might be right up your alley.
  • Some humidifiers have very large capacity tanks. This is great if you need a humidifier that lasts through the night without shutting off, like TaoTronic’s 4-liter tank. However, if filling a large tank will be physically difficult for you or another person using the humidifier, you’ll want a smaller option like Honeywell’s one-gallon Germ Free Cool Mist Humidifier.
  • How many hours would you like your humidifier to run? The Pure Enrichment MistAire runs for 16 hours on a single fill; it’s perfect for long days in your home office. The TaoTronics Humidifier can run for up to 30 hours on low, so you can set it and forget it for half the weekend.
