I have the predecessor that was black in color. It's 3 years old and still works great. Definitely evaporates lots of water into the air. The reservoir must be filled 2 to 3 times per day depending on how often your furnace comes on. It's somewhat of a chore but I get used to it. Keeping the household humidity at 60% or better surely makes lower thermostat settings tolerable so it's a money saver in that regard. The unit uses about 100 watts during its intermittent runs.
Mine is so accurate that it is almost perfectly synchronized to furnace operation. Furnace comes on and shortly thereafter the Lasko humidifier starts up. Furnace shuts off and shortly thereafter the humidifier shuts off. I presume the same accuracy is maintained in this newer white model.
These do use disposable paper filters. I use 2 per season. Cheapest source for the filters is direct from Lasko. I bought a box of 10 for $50 right after I bought the humidifier and I've got about 5 filters left. Even if you throw away about half of them, you'll save money compared to single filter prices at brick and mortar stores. The shipping was free at the time. Maybe it still is.
Humidifiers require periodic maintenance. These Lasko's are no exception. Each year, I sit the thing in the bathtub and fill it's reservoir with vinegar/water and let it run about 30 minutes. This dissolves or loosens the mineral deposits. After rinsing, I then fill it with a bleach/water solution and let it run about 30 minutes to kill mold spores and dormant bacteria.
That yearly demineralizing/disinfecting is somewhat of a chore but I only have to do it once. That's enough to get me through the entire heating season.
All humidifiers require some maintenance--even the ones connected directly to your furnace. I've read operator's manuals for most every one of the furnace mounted units and some of the maintenance procedures are complex and labor intensive compared to the little bathtub routine I've developed for this Lasko.
When I think I will install a furnace mounted unit I search the internet and read the reviews and realize why I put up with this Lasko cleaning routine. Many of those furnace mounted units require demineralizing and disinfecting just like the Lasko--except that I can put the Lasko in a bathtub and keep the mess contained. If I had to rinse and clean a furnace mounted unit, I'd have to use a wet/dry vac to sop up the spillage all over the basement floor, I'm sure. On top of that mess, it seems that furnace mounted units die at an early age due to mineral deposits that can't be controlled.
When the temperatures drop to about 15°F or below, our furnace runs a lot. The more the furnace runs the more the Lasko humidifier runs. I'm sure I have to fill the removeable reservoir 3 times a day or more. It seems to be sized so that a full reservoir lasts about 8 hours. That's enough to get a full night's sleep. Actually, the removeable reservoir holds about 8 hours worth. There's another several gallons in the base to supply the unit with water so you can easily stretch it to 12-14 hours between fillings. I do it all the time. It's just that if you stretch it to 12 hours or more, you'll have to fill the removable reservoir 1.5 times to completely "fill 'er up" again.
All in all, I don't think I could live without a humidifier. We feel warmer, the children cough less while sleeping, there's no static electric sparks when we touch objects or each other ... it's worth the hassle, I think.
This unit says it will do a 3200 square foot home. I guess that's so, but, it's quite nicely sized for homes smaller than that because it won't have to run on high to do the job. Buying the biggest humidifier means you can run the fan on low so it's as quiet as possible.
Once a year I also take it apart to clean the dust from the fan blades and the vortex shroud. This isn't absolutely necessary but it makes it look new again. About 6 or 8 screws removed lets the thing come almost entirely apart for cleaning.
So, a humidifier takes some work no matter what type you get. For a household humidifier, I like this Lasko but I've also got a wife and kids to share in the task of refilling it 3 times a day.
I'm a home handy man so I'll be able to replace the motor in this thing when it goes bad. I don't think it will cost much.
Lasko sells parts and that's what I truly love! Unlike other companies, Lasko actually has parts available and they sell them at reasonable prices.
We use Lasko ventilation fans year round as a sleep aide to produce "white noise." I've got a remote controlled fan that I've come to depend on. After about 4 years of daily night time use, I needed a motor for it last year and, sure enough, Lasko sold one to me and the cost was about 1/3rd that of a new fan.
For the home do-it-yourselfer types, Lasko is the only way to go because they sell parts. Other companies, like Holmes, don't stock any parts at all. Once the complete Holmes unit comes from Taiwan or Sri Lanka to your store's shelf, that's it--you can't get a part even if it was missing from the package before you bought it.
Lasko has a respectable warranty and they don't charge a fee. Holmes and other companies like them charge you a fee that they call "handling" just to get a warranty remedy. That "handling" fee is usually 2/3 or more the cost of a new fan. In other words, you have to pay to return the defective item to Holmes, you also have to pay that "handling fee", and then they might send you a replacement. Lasko doesn't do that. I think that they do require that you ship the item back to them at your cost.
This is a recirculating type of humidifier so it doesn't throw white dust all over everything. The other type of humidifier uses heat to evaporate water (like a distiller) and in the process, all of the minerals of the water become airborne grey-white dust. I don't like that idea. These recirculating types just trickle large quantities of water through a paper filter. The filter retains the minerals.
I remember as a kid, about 45 years ago, I used to sit on my grandmother's floor and enjoy the breeze from a "ottoman" style fan and it had the name "Lasko" on it. I used to think it had something to do with Alaska. I presume it's the same company--still making fans and things that circulate air.

After much researching, reviewing and head scratching, we chose the Oransi v-hepa Max Air Purifier as we require a very clean environment due to medical conditions. There were less expensive units out there but we were looking for long term reliability and service and one that REALLY cleaned the air. The Oransi looked best and it really is. Very well built, quiet running and effective. I am so pleased that we found this unit and purchased it. The shipping and delivery were as promised. I had a couple of questions and their Customer Service responded amazingly fast. Happy we have it!!!!!
