Crane Drop Shape Cool Mist Humidifier

Posted in

I purchased the Crane cool mist humidifier in December 10 and it works great for many months. I've read some of the negative reviews which I almost didn't purchase this machine but I'm glad I did, because it works really well for a mid size/capacity humidifier.

First of all, This humidifier has used a 2.3 gallon per day maximum output with a 0.9 gallon tank. Amazon's initial title for this mentions daily output capacity rather than tank size. This may be confusing, although the correct specs are prominently listed on the Amazon page - fifth bullet point in the "product features" section. The reviewers
complaining about the "misleading name" should try emailing Amazon suggesting a title change on their website... instead of writing a 1 or 2 star review of the product. That would be more helpful and more fair.

As for the product itself:

A few buyers obviously received defective machines; this has to be expected on some level with any manufacturer.

But having read over the negative reviews, I realized that most of the complaints were due to improper use of the machine.
It is essential to read the instruction manual and use the machine as intended by design. Doing so will avoid the pitfalls described by most of these 1-2 star review writers. For reference, I have addressed their most common complaints below:

1) White dust buildup in the room: use filtered or distilled water. This is important if you have hard tap water. (85% of American homes do.) I run my tap water through a Brita filter; the exchange ion resin lowers the concentration of calcium carbonates, accordingly softening tap water. It also helps keep the humidifier cleaner by removing organic impurities, and I have had no white dust buildup.
***If your water is particularly high in mineral content, you should use distilled water, or else opt for a vaporizer-type (humidifying) machine, which creates water vapor free of white dust.***

2) Limited effectiveness: you are trying to humidify too large a room. In my

Four Types of Ionization Air Purifiers

Four Types of Ionization Air Purifiers
Normally, people are unaware that there are four differences of ionic air purifiers in use nowadays. Ionizers in general have been around for many years.

Definition of an ion: an atom or molecule, electrically charged, which has lost or gained one or more electrons, making it either positively or negatively charged.

A simplified explanation of the process. The ionic purifier produces an ions then ions collide with and attach themselves to particles in the air (opposite charges attracted). The particles attach themselves to other particles, collection devices or filters or solid surfaces and removed from the air. The exact process depends on the type of ionic air purifier used.

Ionization is produced and present around you in the air we breathe outside. Ions are measured by how many present in a cubic centimeter. "Typical" clean air outside contains 3,000 positive+ and 4000 negative - ions per cm3. This amount can be influenced by a myriad of factors and is constantly changing and constantly replenished by sun, wind and storms.

By the research that the natural balance of ions outdoors is generally better than most of our indoor environments.

Have you ever felt like getting outside to get a breath of fresh air? Interestingly enough, some scientists point to +/- ions as part of the reason for outside air "feeling right". Unfortunately indoor air generally presents a problem for ions. In most cases the number of ions present is much less compared to outside air.

Sometimes there are too many positive ions and an imbalance occurs in house. Generally the imbalance leans towards the positive but another problem could occur if too many negative ions are present. A balance is the best just like outside.

Ok, great you say, now what about cleaning the air with air purifiers....

These are Four Basic Ionic Air Purifier Technologies:

1. Electrostatic precipitators and charged media filters: mainly passive technologies; most of the ionization occurs inside the air purifier. As air enters the purifier, an electronic charge is

Customer Reviews
Ultra Load,
by Amanda King
For the first time, It's bigger than it looks in the pictures: Stands about thigh-high. This put me off at first but then I plugged it in.
First impression: It's not doing anything then After two days: I want to have it's babies.

I have allergies miserable miserable allergies and I just moved back to Maryland during the worst allergy season I've seen in years.
To a house with three smokers. And Two Dogs. And Two Cats. This house has clutter (re: dust) and mold and four plants in the livingroom and old carpets. It has old furniture and crummy filters but it DOES have ceiling fans!

This house is allergy hell and this purifier? Ah!!! I swear I can breathe again. It cleans up the air (auto setting rocks!) of the entire 500 sq/ft first floor from *awful* to *clear* in roughly 20 minutes, and if it's running constantly, it never gets intolerable. In fact, it barely ever gets to worse than "do you smell something?" for more than a minute or two, even if there has been cooking and smoking and the dogs were in the rain.
Even if it only lasted 6 months before it totally broke down, it would be worth the price to pay every six months to get another one.

I am in love.
Make more of these.
Buy it. Buy ten and give them to your friends. Send this link to anyone with allergies. Or gas.
