Shop for Building Materials at The Home Depot. This Evaporative Air Cooler, Humidifier, and Fan with Ionizer is versatile, lightweight and economical. The Cooler easily rolls from room to room for use anywhere in your house or office. This Air Cooler shoots a stream of air with oscillating louvers, to evenly distribute refreshing cool air. Can also be used as a fan or humidifier if temperature is not an issue. - plus get the air cleaning benefits of the ionic air purifier. The remote control allows you to easily change settings. The Air Cooler works by endothermic reaction (a reaction that consumes heat), so this evaporative Air Cooler sucks air through a wick saturated with water. As the air flows through the wick, some of the water evaporates into the air, consuming the heat that was in the air. An air stream is then blown out the front of the unit and is considerably cooler than the current room temperature! This is not an air conditioner and therefore uses much less energy. Note: This unit is best used in dry climates or open spaces. Leave window/door open when temperature or humidity rises in the room. Add as much ice as possible and set unit next to you for best effect.

The Air Systems BB50-CO standard grade-D breathing-air filtration system is a portable source of breathing air for up to four workers in environments where the air quality has been compromised. The four respirator couplings on the unit have safety locks to secure the breathing hoses (not included) to the filtration unit. Air is moved into the unit by a compressor (not included), where it is filtered in three stages to provide grade-D quality air as specified by ANSI/Compressed Gas Association (CGA) air quality standards. Through three filtration stages, the unit removes approximately 99.99% of airborne contaminants down to 0.01 micron. The first stage removes bulk liquid and particulate matter; the second stage removes oil and ultra-fine particulates, and the third stage eliminates organic vapor and odor. Each filter indicates when it needs to be replaced. The first- and second-stage filters automatically drain. The third-stage filter requires manual draining. The Air Systems BB50-CO comes with an inline carbon monoxide (CO) monitor that detects when CO concentration levels exceed 10 parts per million (ppm) and sets off a warning light and alarm to alert workers. The system's case is aluminum and has a built-in handle for portability. The system includes a pressure gauge, a pressure regulator for controlling air flow to the respirator masks, a visual flowmeter that confirms air is flowing to the CO monitor, and a remote DC alarm jack with cover cap for attaching an optional remote alarm. A safety-release valve at the outlet keeps system pressure from exceeding 125 pounds per square inch (psi). A manufacturer’s warranty guarantees against defects in workmanship or material for one year after the date of purchase when used as directed by the manufacturer. Electrical systems and components are covered under warranty for 90 days from the date of purchase. The CO monitor and sensor are covered under a two-year warranty. The system comes with an instruction manual. Specifications Weight 26.4 lb.

Breathing-air filtration systems provide breathable air to a specified number of users in environments where the air quality is compromised. The system filters incoming air from a compressor to remove particulate matter, oil, odor, and other contaminants. A respirator mask is connected to the unit's respirator couplings, and the filtered air is then fed through the breathing hose and into the mask. The size of the breathing unit required by a particular job is determined by the air flow and pressure requirements of the respirator masks, as well as the number of masks that need to be attached. Air Systems International manufactures air filtration systems, air compressors, confined space ventilation products, and other safety equipment for industrial, military, and emergency-response applications. The company, founded in 1984, is headquartered in Chesapeake, VA, and meets International Organization for Standardization (ISO) 9001 standards for quality.

Breath is the bridge which connects life to consciousness, which unites your body to your thoughts. Inherent to this process is the air quality you breathe. Using the Holmes HAP726-U True HEPA Air Cleaner is a major step (actually 2-in-1) toward making indoor air fresher and cleaner.True HEPA filters will capture a minimum of 99.97 percent of the airborne particles that are up to 0.3 microns -- which is sufficient for most irritatants -- and must be replaced every 6 months to a year and are typcially effective for seasonal allergies. They work at filtering airborne particles that pass through the filter. HEPA filters will not help filter particles that have already settled onto surfaces.This Holmes Allergen Remover is up to 99.97% efficient in removing allergens such as pollen, dust, mold, pet dander and smoke from the air passing through the filter. It also helps fight common household odors with the power of Arm & Hammer Baking Soda.The allergen remover features an understated design that adapts for upright or side placement. It fits nicely against a wall or into a corner, though it is small enough to rest on tabletops too. CADR-rated, the allergen remover accommodates medium rooms up to 256 square feet in area. A GE motor powers the allergen remover and four speed settings enable output options for the room's needs. The digital panel displays a timer for preset intervals of operation. An electronic filter monitor indicates when filters need replacement.

5000 Collection 5000 DX-S UV HEPA and Carbon Air Cleaner with 27 lb Deep Bed Carbon Filter Specifically for Tobacco Smoke with UV SterilizationThe 5000 DX-S UV is part of AllerAir s series of air purifiers designed to remove the harmful toxins and odors associated with cigarette smoke. This unit s 3.5" deep, 27 pound carbon filter provides even more aggressive filtration than our DS series, and is ideal for smoky environments. Designed with a UV light for additional protection against bacteria and airborne pathogens.What differentiates the 5000 Series air cleaner from other units on the market is its advanced design, and especially the quality and quantity of its activated carbon. Activated carbon is the only safe, cost-effective way to trap noxious gases and odors. Activated carbon has been treated with oxygen to open up millions of tiny pores between the carbon atoms. The tiny pores provide an enormous surface area to trap chemicals, which are attracted to the activated carbon. Unlike the 5000 Series, many other air purifiers offer mere ounces of carbon, or carbon-treated filters that simply can’t efficiently adsorb the dangerous airborne toxins. For chemicals, gases and odors carbon is key.The AllerAir DifferenceAllerAir is proud to offer air purifiers that feature the deepest carbon beds on the market, made up of actual granular pieces of carbon, not crushed carbon. The lifespan of their carbon is far greater than many competitors, and has an unparalleled absorption capacity. AllerAir units have metal housing, not plastic ones, and are designed with powder-coated paint, preventing any off gassing. Their carbon filters are also lined with two additional pre-filters, providing increased filtration, and extending the performance of the HEPA filter. The carbon canisters are also refillable,
