An In-Depth Look at Air Filter Manufacturers

!±8± An In-Depth Look at Air Filter Manufacturers

Because there are several air filter manufacturers on the market, it is helpful to be able to sort through the different manufacturers and products. The brief manufacturer/product profiles below are intended to help consumers do just that.

Honeywell

Honeywell dates back to 1885, and produces thermostats, air cleaners, humidifiers, and more. They offer four types of air filters: Replacement Media filters, HEPA air cleaners, Media Air Cleaners, and Electronic air cleaners.

Honeywell's Whole-House HEPA Air Cleaner provides a powerful, three-stage filtration process to deliver the cleanest air. The three-stage filter system includes activated carbon, pre-filter and HEPA filter. These filters contain an AIRWATCH indicator, which reminds when to change filter, and come with a one-year warranty. The Honeywell's Electronic Air Filter destroys almost 98% of pollutants and comes with a 5 year-warranty. Honeywell also offers two types of Media air filters: Furnace Mount Air cleaners and Return Grille air cleaners.

K&N

Unlike traditional disposable filters, for over 30 years K&N has been manufacturing air filters designed to achieve high, virtually unrestricted air flow and long engine life. K&N offers Replacement air filters that fit exactly into the standard OEM (Original Equipment Manufacturing) motorcycle air box, Universal air filters for racing vehicles, and more. There are almost 1000 shapes/styles of Universal air filters, each of which come under a one-year warranty.

Air Bear provides both whole house air cleaners and portable air cleaners, which facilitate cost efficient air filtration. Three sizes are available with three different dimensions 3x6x15, 5x20x25 and 20x20x5. The cost of Air Bear filter ranges from 0 to 0 depending upon the size and dimensions of the filter.

Hunter Air Filters

Hunter manufactures two distinct lines of air filters called the QuietFlow line and their so-called popular HEPAtech line of air purifiers. The HEPAtech filters use a combination of cleaning technologies, with a charcoal filter to remove odors in the house. Charcoal filters must be replaced regularly. The QuietFlow air filters are based on HEPA filters, which also need to be replaced regularly, at least once a year, for effective filtration. The cost of these two types of filters ranges from to .

Oreck

The US-based Oreck offers a powerful Oreck XL Professional Air Purifier, which completely regenerates the air in a 30'x 30' room every hour by capturing and destroying bacteria, pet dander, household dust and allergens. This filter traps 95% of airborne particles, some as minute as one thousand times smaller than a single hair. The light in the filter indicates when the filter needs cleaning. There is five-stage purification process in the Oreck XL Professional Air Purifier, which makes it more powerful than HEPA filter in air filtration. The five-stage system contains a pre-filter, positive charging wires, a collector, charcoal odor absorbers and an air-revitalizer, which say goodbye to all dust mites, and airborne allergens.

How The Body Reacts To Extremely Cold Environment

!±8± How The Body Reacts To Extremely Cold Environment

The human species belong to the categories of warm-blooded mammals, meaning we are capable of maintaining homeostasis by keeping our body temperature roughly at constant level regardless of the ambient or environmental temperature and involves our body's ability to cool down or produce more heat. Temperature regulation also includes regulation of metabolism, either by increasing or decreasing it.

However, like machines, our body has limitations that when exceeds it limit, more than the body can endure, our body's use of its defense mechanism against harmful stimuli deteriorates and losses its function. When subjected to an extremely cold environment for example, more than it can handle, our body will suffer from hypothermia wherein the body's core temperature falls below the required level for normal metabolism to produce more heat. As the body temperature drops, the body' defense is to shiver as an attempt to generate heat. However, if our body fails to thermoregulate, mental confusion and other debilitating complications such as loss of a limb or body parts and even death can occur.

Treatment of hypothermia varies according to the severity and location of the affected area as cold injuries can be categorized into non-freezing, freezing and the worst is hypothermia. Non-freezing injuries include chilblains, immersion foot and trenchfoot. Freezing injuries consist of frostnip and frostbite.

At the first sign of the body's failure to fight exposure to severe cold, necessary interventions are needed so that the body does not deteriorate. One basic medical intervention is through rewarming which comprises of various methods and provisions such as employing properly insulated clothing, warming device like hot water bottles and baths and being away from the source of cold. More invasive measures include the use of intravenous fluid infusions to induce cold diuresis or dilution and removal of cold body fluids, irrigation of body cavities such as thorax, peritoneum, bladder and the likes, with warmed fluids.

Suffering from the ill effects of exposure to cold is definitely has its deleterious effects and more costly compared to a few and basic preventive measures. If the temperature drops too low, keeping the doors and windows close, having layers of clothing and blankets around the body will help but will not suffice to keep the body at its ambient body temperature once the air gets too cold beyond the body's tolerance. Aggressive and non-aggressive treatments, invasive and non-invasive, matched by the degree of hypothermia is way too far and way too expensive compared to a well-functioning centralized heating system that will come handy during winter season.
