Smoke Damage >> Get Rid Of A Fire Smoke Smell In The Walls

Makers of ozone generators often target home users with claims that the devices reduce allergens such as dust, smoke, pollen, germs, and mold using "highly activated oxygen" or "super oxide ions," leaving the fresh scents of thunderstorms and waterfalls in their place. Two companies, Biotech Research and EcoQuest, Get Rid Of A Fire Smoke Smell In The Walls go much further in their ads. 

The $850 EcoQuest Fresh Air uses "exclusive 'Space Certified' " technology "used to scrub the air inside spacecraft," ads say. BioTech Research says its $230 EdenPure Are's technology is "used by the federal government to purify air in the Space Shuttle and Get Rid Of A Fire Smoke Smell In The Walls the International Space Station." 

And ABC Radio broadcaster Paul Harvey, Get Rid Of A Fire Smoke Smell In The Walls who claims to use the EdenPure, describes it as "the best air purifier ever created by the hand of man" in an ad. But our tests found that even at the generators' low everyday settings, their ozone production quickly exceeded the 50 parts per billion (ppb) FDA limit for medical devices. 

Purifiers aren't considered medical devices by the FDA. Ozone concentrations in our test room measured about 650 to 990 ppb for the EdenPure, Get Rid Of A Fire Smoke Smell In The Walls depending on the setting. The EcoQuest produced about 110 to 350 ppb at its normal and high settings and up to 4,300 ppb at its "away" settings, which the company says to use only when you and your pets aren't home. 

The U.S. Environmental Protection Agency warns that relatively low levels of ozone can cause chest pain and shortness of breath. Ozone may also worsen asthma and compromise the ability of the body to fight respiratory infections. The EPA regulates outdoor ozone levels, Get Rid Of A Fire Smoke Smell In The Walls but there is no federal agency that regulates indoor levels or air purifiers. 

As we went to press, Get Rid Of A Fire Smoke Smell In The Walls California banned the sale of ozone generators for most uses. Because both of these ozone generators produced very high amounts of ozone and have no way to automatically control its concentration in the air, we consider them Not Acceptable. They were also poor at removing dust and smoke in the air. 

About those "space" claims: We sent NASA the ads, and spokeswomen told us that the space shuttle and Get Rid Of A Fire Smoke Smell In The Walls the space station life-support and environmental control systems have always relied on filtration to purify the air, not ozone. No air purifier alone will clean the air. Nor should it be the first thing you try. 

Based on increasing concern about exposure to even small amounts of ozone, we strongly suggest using whole-house and Get Rid Of A Fire Smoke Smell In The Walls portable air purifiers that rely on filters and produce no ozone. At their lowest and quietest settings, the top-rated portable air purifiers outperformed or matched most of the other portables in the Ratings. 

There's no reason to choose any others. Stick with whole-house systems if you have forced-air heating. The top-rated furnace filters are a simple, inexpensive upgrade from the standard furnace filter. For performance comparable to that of the best portables, Get Rid Of A Fire Smoke Smell In The Walls opt for a professionally installed system. 

Ventilation is still the best way to remove odors from your home. Although our latest tests show that the IQAir (20) and Austin Air (21) removed cooking odors, Get Rid Of A Fire Smoke Smell In The Walls that capability will be reduced with use. And those models aren't very effective at removing dust or smoke. The Ratings rank air purifiers by overall performance. 

Quick Picks lists models that combine performance and Get Rid Of A Fire Smoke Smell In The Walls value. QUICK PICKS Best room air purifiers: 1 Whirlpool $230 2 Kenmore $270 Both combine fine performance with quieter operation, especially when set on low. The Hunter (3) costs a bit less in annual costs but was noisier when run on high. 

Though the Friedrich (28) and Kenmore (29) were better at dust removal on their high settings, Get Rid Of A Fire Smoke Smell In The Walls they emitted moderate amounts of ozone in our tests, so we don't suggest you buy them. Best whole-house air purifiers: 1 Lennox $350, CR Best Buy 9 3M $20 103M $16 The Lennox is the only professionally installed system that does not produce ozone, and it's also the least expensive. 

But it will cost an extra $200 or more for installation and has high annual costs for filter replacements. Do-it-yourself furnace filters like the 3M (9, 10) aren't the best if you live with a smoker, Get Rid Of A Fire Smoke Smell In The Walls but these two were very good at removing dust without significantly limiting the heating/cooling system's airflow. 

For the past 15 years, CONSUMER REPORTS has recommended some electrostatic precipitators. The Friedrich C-90B and Aprilaire 5000 were effective air purifiers with low annual maintenance costs but produced small amounts of ozone. These portable Get Rid Of A Fire Smoke Smell In The Walls and whole-house purifiers apply an electrical charge to the particles drawn into the device and produce some ozone as a byproduct. 

These products' performance has not changed significantly, Get Rid Of A Fire Smoke Smell In The Walls but our advice has. We now believe that air purifiers that emit even small amounts of ozone (less than 50 parts per billion) are not your best choice. Research is increasingly warning against adding ozone to indoor air. But more studies need to be conducted to determine the effects of low-level ozone exposure. 

If you own one of these models, Get Rid Of A Fire Smoke Smell In The Walls we suggest that you err on the side of caution. If a member of your household has asthma or allergy symptoms that aren't improving, even though you've removed allergy and asthma triggers and keep your home well ventilated, you might want to consider switching to one of our highly rated, filter-based models if you still want a purifier. 

Overall score is mainly how well models removed dust and smoke from a test chamber, Get Rid Of A Fire Smoke Smell In The Walls plus quietness for room models and airflow resistance for whole-house. Dust and smoke are how well models cleared the air of fine clay dust and cigarette smoke. Pollen removal is typically similar to dust removal. Noise for room models denotes instrument and panel judgments at highest and lowest speeds. 

Airflow resistance reflects how freely air passed through the unit. Annual cost is Get Rid Of A Fire Smoke Smell In The Walls our estimate based on continuous operation. Ozone emission is our classification of ozone generated by a product in our tests: 1 to 25 parts per billion (ppb) is low (L); 26 to 50 ppb, medium (M). 

For whole-house products, Get Rid Of A Fire Smoke Smell In The Walls ozone calculations are adjusted to be comparable to those for portables. Price is approximate retail. Scores for previously tested models may have changed based on the performance of newly tested models and testing changes.
