Humidifiers are very beneficial device that is use to increase moisture in the air. This device is particularly useful in winters or when climate is dry. If your kids have cold or flu, then humidifiers make it easy for them to breathe. Humidity level in your home should be in the range between 30 percent to 60 percent. If the level of humidity is not in this range, then you may experience health problems.

Low Humidity: If the humidity level drops below 30%, you may experience dry skin, irritates nasal passages, causes eyelids to itch, and when you sleep, you might mouth breathe making your mouth and throat dry.

High Humidity: If there are lots of moisture in the air and the humidity level increases above 60 percent, then you may experience warm and suffocating. High humidity activates unsafe bacteria, mold, mildew, and dust mites.
To resolve the problem you will need either a humidifier (that adds moisture to air) or De-humidifier (that reduce level of humidity). In this article we will discuss about humidifiers.

Type of Humidifiers

Basically, there are three main types of humidifiers available in India:

  • Tabletop
  • Console
  • In Duct (whole house)

Table top humidifiers such as crane cool mist humidifier,are by far the cheapest. They are suitable for use only in a single room. There are various types of tabletop humidifiers: cool mist, warm mist, and ultrasonic humidifiers.

Console humidifiers are bigger units than the tabletop ones, but they are also portable and can be moved around the house according to your needs. One advantage of the console units is that you don’t need to change the water so frequently. However, they can be noisy compared to the tabletop. Both the console evaporative and ultrasonic types provide sufficient moisture and humidify up to two rooms.

In duct humidifiers are your best bet if you already have a ducted heating system installed in your house. They simply get ducted into the existing system and plumped into the water supply. These are the best humidifiers for adding moisture to your whole house. They have to be professionally installed and are more expensive, but once installed, are the least expensive to run.

Choosing The Best Humidifiers

Before you purchase humidifiers in India, you should be aware of different features that an ideal humidifiers should have. Here are some factors you should consider when buying your humidifier:

Noise Level

Some humidifiers generate more noise than others. If you are sensitive to noise, especially in the bedroom, then you should be careful to choose the less noisy humidifiers. Ultrasonic and warm mist humidifiers are generally quieter in operation than the evaporative types.


If portability is a major factor, then the tabletop or console humidifiers would be the better choice for you since you can move them from room to room. You just need to plug it into an electronic socket to get it working. However, portable humidifiers would only be sufficient to humidify two rooms.

On the other hand, if you are well settled in your own home and live in a larger house, then you should consider the whole house humidifier. The best thing about the whole house humidifier is that it only requires one time installation and minimal maintenance. You do not need to keep refilling the water and it is cheap and efficient to run. The level of moisture in your house is set at one point, require less effort to run.


While the portable humidifiers may seem the best humidifiers to buy in terms of cost, I recommend that you should not only look at price of purchase, but also the cost of operation and its durability.

Cleaning and Maintenance

You should look for a humidifier that is easy to clean and maintain. Note, however that quality and mineral content of your water may impact the level of necessary cleaning for the unit to run properly for a long time.

Some units require cleaning every couple of days or every week.Other units use humidifier filters to help control mineral build up and bacterial growth. These types usually help prevent that white mineral dust from accumulating on your tv and furniture, but you will need to buy replacement filters for these.

Humidity Control

The ideal humidity level is around 45 percent. Too much humidity can cause condensation in the windows, and the growth of mould, bacteria and dust mites. Some humidifiers incorporate a built-in thermostat that helps keep the house at an optimal humidity level, hence prevent too much humidity in the air.

The Top Humidifiers Brands in India

There are many reputable brands for humidifiers, such as Crane, Venta, Honeywell, Air-o-swiss, and Soleus. The brands that I found to be the most popular from my research are Crane, Hunter, Frigidaire, and Honeywell. Honeywell sells both tabletop and console humidifiers and the price ranges from $20-$399. Hunter makes lower priced tabletop humidifiers.

It is advisable to buy a humidifier of a reputable brand as most of the spare parts are easily available, and you will generally not have a problem with service and warranty.


When shopping online, I always look for a warranty and from a well-known company. That is why I tend to shop at Amazon, which happens to also have the lowest price for the best humidifiers. Amazon usually has ranging warranties but you can usually get 3 years if you pay an extra $27, which to me is well worth the money.

WiFi or wireless signals are generally information carriers between two devices known as transmitter and receiver. A WiFi can also extend our senses and enable us to see moving objects through walls and behind closed doors. The growing ubiquity of wireless devices combined with the advent of mobility applications requires businesses to be diligent in managing inference throughout their deployments. The many WiFi technologies and commonplace electric devices already in use and newly emerging impede wireless performance.

What is WiFi

Wi-Fi is the name given by the Wi-Fi Alliance to the IEEE 802.11 suite of standards. 802.11 defined the initial standard for wireless local area networks, but it was considered too slow for some applications and so was superseded by the extensions 802.11a and 802.11b, and later by 802.11g.

802 Network Standards

The IEEE 802.15.1 standard is the basis for the Bluetooth wireless communication technology. Bluetooth is a low tier, ad hoc, terrestrial, wireless standard for short range communication. It is designed for small and low cost devices with low power consumption. 802.11 or WiFi came into existence as a result of a decision in 1985 by the FCC to open several brands of the wireless spectrum for use without a government license. To operate in these bands though, devices were required to use spread spectrum technology. This technology spreads a radio signal out over a wide range of frequencies, making the signal less susceptible to interference and difficult to intercept.
To increase the data rate in the 802.11b standard, in 1998, Lucent Technologies and Harris Semiconductor proposed to IEEE a standard called CCK (Complementary Code Keying). Rather than the two 11 – bit Barker code, CCK uses a set of 64 eight bit unique code words, thus up to 6 bits can be represented by any code word. As 802.11n has become a standard interface on pcs, tablets and smartphones, the applications used by these devices have continued to progress. mobile technology has encountered the next frontier – video. Whether delivering youtube to smartphones or moving HDTV signals around the office or home, video has become a significant driver of network traffic, chiefly because it requires one or two orders of magnitude more bandwidth than other Ip services.

So all life in this planet has been dependent on hydrogen, and I think that we should follow the universe’s example by using the abundant energy that is all around us. (Also we can produce hydrogen cleanly with electricity from solar, wind, and water, without using coal, oil, natural gas, or nuclear.)

So I made the connection that we could be burning hydrogen to cook or melt stuff, and to generate electricity with zero emissions. Then I found out that it’s already happening. There are already stoves, fake fire places, kilns, and hot water heaters being converted to burn hydrogen.

In my book and in my chapter, Burning Hydrogen, Instead of Oil, Coal, or Natural Gas, I am advocating for converting all steel smelters, pottery and brick kilns, water heaters, heaters, and factories to burn hydrogen. (Also hydrogen fuel cells can power electric pottery kilns and electric aluminum smelters.)

Many of these ideas are starting to manifest and here are some videos I found on Youtube that either demonstrate that these ideas are already happening or prove that they could be done if we apply existing technology into different applications. I found out the all cars can be converted to burn 100% hydrogen gas and they clean the air as they drive, by burning up existing pollution as it goes through the Hydrogen flame in the engine. Here are 2 videos of Roy McAlister the President of the American Hydrogen Association, who has been converting cars to hydrogen for 45 years, driving one.

I also occurred to me that we could be converting all existing coal and natural gas power plants to burn hydrogen, by just changing the burners and the fuel, which would be easier than taking the time and money to build all new power plants, and it would instantly make all grids 100% zero emission. If we woke up to this possibility we also would no long need to waste billions on dangerous nuclear power plants, that take years to build, are expensive, produce deadly waste that lasts for millions of years and can be turned into nuclear weapons, and that are vulnerable to terrorism and natural disaster, like earthquakes, like what just happened in Japan where an earthquake a tsunami as caused a terrible accident.

This video is of a guy starting up the hydrogen/oxygen flames of a very large artificial gem kiln, which shows that we could be doing the same in power plants. In the video below a guy is boiling some water with a hydrogen and oxygen flame and stove, which is what coal, natural gas, and nuclear power plants do. They boil water and the steam turns turbines, which generate electricity, thus it proves that this idea is possible and safe.
