How are smells removed from charcoal

The truth about activated carbon filters in the home

How activated carbon filters work and why they are not always the method of choice

Activated charcoal is considered a panacea when it comes to bad air or bad smell. There is also a reason for this: due to the special properties of specially prepared carbon (activated carbon), an activated carbon filter acts like a kind of sponge and can bind many dangerous substances. The activated carbon filter has its particular strength in water and therefore plays an important role in the food industry, for example, to filter substances that are hazardous to health.

This "good reputation" of the activated carbon filter has meant that such filters are the first choice for most manufacturers when it comes to filtering air. Because the mode of action is recognized and plausible.

What most manufacturers do not tell you: the effectiveness of carbon filters is limited.

Once the recording capacity is exhausted, the filter stops working. If this is used to filter bad smells, not only will it not filter any more smells from this point on, but it will even become a source of bad smells itself.

With smaller activated carbon filters, this point can be reached in just a few weeks!

In order to ensure its effectiveness, the activated carbon must be renewed regularly.
What is absolutely necessary in the food industry and ultimately paid for by consumers through the purchase price is an annoying and, in the long run, costly evil for the private user if the only thing that matters is to get rid of bad smells or to avoid them.

Especially since there is a second unpleasant truth that is little talked about:

The effectiveness of activated carbon filters in filtering bad smells also depends on the contact time of the contaminated air with the activated carbon. With an extractor hood or vacuum cleaner, however, the air is pushed through the filter very quickly.

A complete absorption of the odors can usually hardly be guaranteed in this short period of action.

A further complicating factor with a vacuum cleaner is that the downtime since the last use, sucked in dirt (especially the organic components such as leftover food or hair) has already accumulated a lot of bad smell through decomposition processes.

When the vacuum cleaner is switched on, it is pushed through the filters far too quickly for the odor to be completely adsorbed.

et project “TheOlfactory” extensively investigated the problem of filter systems for odor avoidance in practical tests with vacuum cleaners in cooperation with Siemens / Bosch more than 10 years ago.

The active ingredient SinoAir, which has proven itself in the industry against bad odors® does not work solely by binding bad odors, but uses the property, To break down odor molecules through natural, accelerated oxidation. The effect not only unfolds at the moment of use, e.g. with a filter mat, but becomes like the smell itself, spreads constantly in the air and acts through natural diffusion continuously in the whole room.

The special active ingredient for extractor hoods from SinoAir that is now available on the market® is called Liquid filter and is particularly for Circulating air extractor hoods thought. [see also: Liquid filter for extractor hoods]

The highlight: You can even leave used activated charcoal filters in the extractor hood. Liquid filter is simply sprayed on and removes all negative odors from the activated carbon filter. The active ingredient is then gradually distributed throughout the room / apartment via the extractor hood and develops its odor-destroying effect - even with odors that have already diffused into walls and textiles.

With liquid filter from SinoAir® virtually turn your extractor hood into a high-quality (odor) air purifier!

Our tip:

Even if the Liquid Filter was specially developed for the extractor hood, the active ingredient can also be used for other purposes: Simply put two or three puffs in your rubbish bin or in the old plastic recycling sack / container. You will be amazed how quickly SinoAir® works!

Are you perhaps a smoker and do not want your visitor or your life partner to be bothered by the smell of smoke only? Simply spray 3 puffs on ... your fan-assisted hood and let it run for 15 minutes ... even if you are not cooking at all.

Our insider tip:

Do you have a bagless vacuum cleaner? Just give it …. in the ... and your vacuum cleaner won't smell any more ...
