If you’re looking for a top-quality ultrasonic humidifier, two Air-O-Swiss models deserve serious consideration. Consumers Digest Magazine recently gave the Air-O-Swiss 7133 one of its highest ratings, while across the road, Consumer Reports gave similar high marks to the slightly more expensive Air-O-Swiss 7135.
Both units feature warm or cool mist humidification. Both Air-O-Swiss humidifier models are also very quiet (perfect for running at night during sleep.) Both Air-O-Swiss units are designed to cover rooms up to 600 square feet and both feature powerful ionic systems to help prevent and control microbial growth.
Actual Users give the Air-O-Swiss generally favorable reviews. Here is one buyers detailed report:
“A Salesman introduced this Air-O-Swiss as the best machine on market. He added Venta-Sonic does the same job but costs $50 less, and all other brands can’t compare. I bought both units to compare. Air-O-Swiss is a clear winner, hands down.
1. Consistent Performance – I can put Air-O-Swiss on automatic mode with preset humidity level before I go to sleep, when I wake up, my bedside humidity reader (far away from the machine) has within 1% margin of error to the preset desired level.
2. Greater Output Capacity – My bedroom is 300 square feet+, half of 600 both machines claim can cover. Air-O-Swiss comfortably reaches my desired level (b/w 40% and 50%) with lower settings (It can go as high as 75%, I only set it up to 50%). Venta-Sonic labors over 8 hours at MAX settings and gets me LESS humidity! It won’t get me above 50%.
3. Ease of Use with Digital Control – I like Air-O-Swiss’ Auto Mode with Desired humidity setting. The machine adjusts output automatically. Venta-Sonic only has two dials, you’ll have to experiment for a while to find the optimal settings. As soon as atmospheric humidity changes, which can be daily or a few hours, you’d have to re-adjust again…that’s like shooting darts in the dark all the time, you can get close if lucky but never on target.
4. Better Mist Venting Notch Design – I put both machines on 3-feet-tall dresser. Air-O-Swiss’ notch is tilted higher than Venta’s. This means when operating cold mist, Air-O-Swiss’s disappears into air vs. some Venta’s still hit the floor – not enough to form condensation but less efficient in humidifying – perhaps that contributes to Venta’s lower output previously mentioned.
5. Better Craftsmanship – Venta-Sonic is a notch below Air-O-Swiss, appears to be made simpler and CHEAPER.
Anything Air-O-Swiss can improve? Sure! The humidity reader on the machine is adjusted about 13% lower than actual average room humidity. They probably did it to ensure average humidity far away from the unit reaches target, but I think they can do so internally without having to show it. It would be a mistake to read the room humidity off that machine.
After I got the machines, I googled on both. There was one review elsewhere saying that Venta-Sonic broke after a month and half, out of store 30-day warranty and owner took a loss. Air-O-Swiss has 3 year warranty, if I remember correctly, Venta 1 year.” –T.L.
