While it seems straightforward enough, some overlap exists that may make it confusing when deciding between a standard household fan or a stronger commercial fan. Then there are various types in each category that could require additional consideration. This article will outline some basic guidelines for choosing the right fan for your space.
Portable Space Electric Heaters are typically used when the main heating system is inadequate or when central heating is too costly to install or operate. In some cases, small space heaters can be less expensive to use if you only want to heat one room or supplement inadequate heating in one room. They can also boost the temperature of rooms used by individuals who are sensitive to cold, especially elderly persons, without overheating your entire home.
Space Convention Heater capacities generally range between 10,000 Btu and 40,000 Btu per hour and commonly run on electricity, propane, natural gas, and kerosene (see wood and pellet heating for information on wood and pellet stoves).
Although most space heaters work by convection (the circulation of air in a room), some rely on radiant heating. Radiant heaters emit infrared radiation that directly heats objects and people within their line of sight, and are a more efficient choice when you will be in a room for only a few hours and can stay within the line of sight of the heater. Oil Filled Heaters can also be more efficient when you will be using a room for a short period because they save energy by directly heating the occupant of the room and the occupant's immediate surroundings rather than the whole room.
Safety is a top consideration when using space heaters. The U.S. Consumer Product Safety Commission estimates that more than 25,000 residential fires every year are associated with the use of space heaters, resulting in more than 300 deaths. In addition, an estimated 6,000 people receive hospital emergency room care for burn injuries associated with contacting the hot surfaces of room heaters, mostly in non-fire situations.
When buying and installing a small space heater, follow these guidelines:
Only purchase newer model heaters that have all of the current safety features. Make sure the heater carries the Underwriter's Laboratory (UL) label.
Choose a thermostatically controlled heater, because they avoid the energy waste of overheating a room.
Select an Electric Stove of the proper size for the room you wish to heat. Do not purchase oversized heaters. Most heaters come with a general sizing table.
Locate the heater on a level surface away from foot traffic. Be especially careful to keep children and pets away from the heater.
Humidifier & Aroma Diffusers are often confused, as the products can look similar on the outside or have similar functions. But there are several important differences between these technologies. If you need more moisture in the air in your home, then you need an Ultrasonic Humidifier. If you only want to add fragrance to the air, and not moisture, then a diffuser is the proper product. Diffusers simply do not hold enough water to impact the humidity level of a room.
Having the right humidity level in your home can help you breathe easier, temporarily relieving coughs and congestion. Moisture in the air can also help temporarily relieve dry skin, dry eyes and chapped lips. Proper humidity has important benefits for your whole house as well, including helping to prevent gaps in hardwood floors, cracks in wooden furniture and static electricity that can harm electronics.
Air Purifiers sanitize the air, getting rid of pollutants, allergens, and toxins; they're different from air filters, which only remove them from circulation. But how do air purifiers actually work?
Air purifiers have a relatively simple set-up: a fan that sucks in air, and one or more filters. These filters — usually paper, fibers such as fiberglass, or a mesh — capture and neutralize pollutants and particles as air passes over them before the clean air is recirculated into the living space.
They are effective at filtering out most polluting particles, although some are likely to still remain on soft and hard surfaces like furniture or walls. The particular airborne particles that get pulled out of the air depend on the type of air purifier and filter used.
Many people are familiar with the daily routine of washing, drying, and styling their hair. Although hair will eventually dry on its own if given enough time, most people reach for a Hair Dryer to speed up the process. While science may have disproven the link between wet heads and catching colds, it's still no fun to sit around with a head full of wet hair, especially in the winter. Hairdryers, also known as blow dryers, were first sold in the 1920s. At first they were pretty dangerous to use -- hundreds of people were electrocuted when they dropped their hair dryer into water-filled sinks and bathtubs.
