You can find a vacuum cleaner in almost every home.The purpose of these machines is to remove dust from your home and provide a cleaner environment for you and your family.

A humidifier is a household appliance that can add humidity to a room, either by humidifying a designated room or by connecting to a boiler or central air-conditioning system to humidify an entire building.According to the heat and moisture exchange theory, humidifiers are divided into the following two types in practical engineering:
1. Equal enthalpy humidifier: it USES sensible heat of water to absorb air to conduct evaporation and humidification, and its changes in enthalpy and humidity diagram are approximate equal enthalpy processes.
2, isothermal humidifier: that is, the use of heat energy to convert liquid water into steam and air mixture for humidification, the change in enthalpy, humidity chart is an approximate isothermal process.
Humidifier from the scope of use can be divided into industrial humidifier, commercial humidifier and household humidifier three categories.

Although there are a lot of people begin to choose to use a vacuum cleaner in cleaning, but also want to know the life of the vacuum cleaner is a must, is not to say that has been able to permanent to be used, sometimes not be damaged, and should be regularly replaced, to clean the room more clean, vacuum cleaner, how long does it take to change a, some people feel especially curious, at the same time for the vacuum cleaner is should understand how to maintain good.

High efficiency particulate air (HEPA) vacuum cleaners differ from traditional vacuum cleaners in that they contain high efficiency filters capable of capturing very small micron-scale particles.A true hepa filter can capture 99.97% of particles larger than 0.3 micron in the air.To show how small it is, human red blood cells are usually between six and eight microns.

The haze reminds the city people again and again, the air pollution has become increasingly serious, the air quality we breathe is getting worse and worse, more and more people are afraid to go out, the appearance of air purifier can purify the indoor air clean, then to introduce the role of air purifier.

Humidifier can create ideal indoor humidity, care for family health.Three basic environmental controls: air quality, temperature, and relative humidity.Relative humidity is the most easy to be ignored, appropriate relative humidity control is also corresponding to the energy saving and work efficiency of one of the important factors.

Common fault detection of humidifier
Household humidifier is mainly ultrasonic - based.Small humidifier to bring us moisture life at the same time, it is also inevitable to encounter some glitches.It is necessary to know some basic troubleshooting methods.

When the vacuum cleaner is working, a stream of air passes through the vacuum cleaner, enters through the inlet, and exits through the exhaust.This airflow carries particles of dust that have been sucked in by the vacuum cleaner.
