US $1-20 1 Unit Transaction Level What's That Stuff In My Ice? We've got an LG French Door fridge. Our ice is cloudy at the center, clear near the edge. When it melts, it leaves little white particles floating in our glasses. Our water is poured from a Brita pitcher, and is clear as a bell until we add ice. We installed an inline filter outside the fridge, but got no joy. We're still getting white stuff in our water. Any ideas on how to fix this? Want to stay up to date with this post?

Adapting Recipes for Instant Pot Sitram Catering line is done Best carbon steel panOn this page you will find a comparison of indoor air quality systems utilizing filterless technology based on Oxidation, Ozone and/or UV light (also see HEPA Filtration, Air Filters and Needlepoint Ultraviolet Light and Ozone receive a lot of attention concerning indoor airBoth are nothing new. They have been used for decades in hospitals, medical applications and the food industry. This technical overview will outline each of the technologies and discuss the pros and cons of each. AHPCO is an Advanced Hydrated Photocatalytic Oxidation technology. Basically, it is a broad spectrum high intensity UV light targeted on a five-metal catalyst in a low-level ozone and moist atmosphere. This creates an advanced oxidation of friendly oxidizers, or very safe and aggressive oxidizers that

revert back to oxygen and hydrogen. The AHPCOCell was developed in 2003. The original AHPCO Cell was designed for use in a central HVAC system.naturopure hf 280 personal air purifier This provides the fastest and most effective oxidizer distribution. hoover air purifier tio2 and improved hydration compounds were added as a catalyst creating a totallymopar air cleaner wingnutA 360 degree cell provided maximum exposure of the catalysts. The bulb was reworked and a HE/UV Broad Spectrum 100-3-NM bulb with a heavy duty filament was developed. This combined with a soft start ballast gave the new AHPCO Cell an unprecedented 3 year, 25,000 hour life. major improvement over the current standard 8,000-10,000 hour UV bulb life.

The most important improvement was the efficacy, the new cell design created more hydro peroxides and super oxide ions and ozone levels were further reducedCountry or forest air usually contains roughly .01-.02 ppmMost people can smell ozone at .01 ppm, and .05 ppm is the federal safe limit for medical devices. The new cell also produces hydroxide ions and ozonide ions which broadened the scope of its air purification capabilities. This technology is used exclusively in the Air This is an advanced oxidation technology that consists of a proprietary, high-intensity broad spectrum UV tube (100 300nm) in a hydrated catalyticLow-level ozone is produced in the cell, the majority of which is converted into airborne hydro peroxides and super oxide ions. is encased in a protective poly tube to prevent any glass or mercury breakage/leakage. Also, the entire assembly is encased in a protective metal cell. Chinese Government has tested and passed the AHPCO Cell for use in preventing

SARS in Chinese subways. An advanced version of this technology is used in Air Oasis Air Purifiers Pros: Low cost, no maintenance (replace cell once every 3 years), easy installation, airborne hydro peroxides, super oxide ions and very low-level ozone (.01 - .02 ppm*) travels through the house providing 24-hour protection against airborne mold, bacteria, viruses, odors and VOCs. acts as a germicidal lamp and treats the air that passes by it. ozone safety limits are .04 ppm. At .01 - .02 ppm the AHPCO Cell is not considered This system utilizes a Titanium grid as a catalyst for UV-C (254nm)Air that passes through the grid and comes in contact with the catalyst is purified by Hydroxyl Radicals that are formed on the TitaniumAlso, the UV-C light rays kill microbials that pass by them. Pros: Effective on the air that passes through the system for mold, bacteria and VOCs. Cons: Expensive, large, substantial installation, and not effective on

Only treats the air that contacts activated target surfaces as it passes through the unit. Most UV systems install a glass UV mercury bulb without protection from breakage. A broken bulb could release mercury, a potential environmental and health hazard. These are rapidly becoming very popular as an easy fix for the air conditioner coil mold problem. This is the most prevalent cause of the building mildew smell you get when you enter an air-conditioned sick building. (254nm) lamps are basically similar to sun lamps and are typically only effective on microbials that pass by within a few inches of the lamp or areas where the light is shining directly on for extended periods of time, such as the air Pros: Low cost, easy installation, and effective on suppressing mold growth on the coil. Cons: Not effective at killing airborne mold unless numerous lamps are used only effective on the surface of the coil that is in direct light.

This leaves much of the coil with no treatment. Does not provide ongoingMost UV systems install a glass UV mercury bulb withoutA broken bulb could release mercury, a potential environmental and health hazard. Minimum of two lamps must be used to cover at least one-quarter of the coil surface (the upper half of the outer coil). For one-half coverage, three to six lamps must be used. Ultraviolet lamps in the 185nm range produce low-level ozone, just as the sun does, which is very effective in odor microbial reduction and VOCs. Pros: Low cost, easy installation, and effective on mold, smoke,The ozone gas travels through the house to provide ongoing treatment, unlike the UV-Germicidal Lamps where only the air that passes within inches of the bulb is treated. Cons: Ozone is a concern to some people. Improper systems could produce ozone levels exceeding Federal guidelines. Ozone does not work on all odorsMost UV systems install a glass UV mercury bulb without protection

A broken bulb could release mercury, a potential environmental Corona Discharge systems simulate lightning with a corona electric arc or spark. Strong ozone is produced by converting the oxygen (O2) to ozone (O3).Ozone effective on odors, bacteria, mold and some Cons: Air is 80% Nitrogen and 20% Oxygen. These units convert OxygenThey can also convert the Nitrogen to airborne Nitric Acid and Nitric Oxide, which can act as an lung irritant and results in a pungent "metallic" or "bleach-like" odor and causes maintenance problems due to corrosion. They can also generate They produce high concentrations and levels of ozone -- erratic, unpredictableozone "blasts" are common -- usually over Federal safeThese systems typically will require expensive monitors to controlAlso, arcing (sparking) can be a noise and safety problem. Note: Corona Discharge Ozone Units should never be used for air purification in occupied areas, as they will usually exceed Federal safety limits of ozone.
