Questions
Questions and answers
Here are answers to the questions readers ask most often: about the guide itself and the former website on this domain, about warmth and humidity at home, and about how to approach claims made for home appliances and products. Each topic is covered in more detail in the themed sections.
If a claim cannot be checked with a thermometer, a hygrometer or a refund, it describes not a product but the buyer's hope.
About the guide
Are you connected with the website that used to run on this domain?
No. This domain used to sell products with claims that were not backed by verifiable data. Nanocomfort is not connected with the former website, does not restore its pages and does not sell or promote its products.
Do you sell instruments or carry out tests?
No. We are an independent guide: we do not sell products, take orders, test instruments or issue verdicts. We explain how the microclimate works and how to check claims for yourself.
Why do you not name brands or publish rankings?
We write about principles, not products. Rankings and advertising go against our editorial rules, and an instrument is best chosen on measurable specifications and return terms that you can check yourself.
What are your materials based on?
Specific values come from the Russian standards GOST 30494-2011 and SanPiN 1.2.3685-21, and information on buyers' rights from the Russian Consumer Protection Law. Other countries have their own standards and consumer rules. Everything else is described in general terms; we do not invent statistics or studies.
Warmth and humidity
What room temperature counts as comfortable?
Under the Russian standard GOST 30494-2011, the optimal temperature for a living room is 20–22 °C in the cold season and 22–25 °C in the warm season. Everyone feels it differently, but these values are a good guide; other countries set their own.
Why is the air at home so dry in winter?
Cold outdoor air holds little moisture, and when it is heated indoors its relative humidity drops even lower. First measure humidity with a hygrometer: for the cold season, the Russian standard GOST names 30–45 % as optimal.
Where does condensation on windows come from?
Moisture from warm air settles on cold glass. Most often the cause is high humidity and poor air exchange, sometimes cold reveals or a frame that does not close tightly. Airing, a working extract and window care all help.
Should a radiator be hidden behind a cover?
A solid cover, curtains and furniture stop heat spreading through the room. If you need a cover for safety or looks, choose a slatted one with good gaps at the top and bottom.
Devices and claims
How can I tell that a claim in a product description is doubtful?
Be wary if the effect cannot be measured, the mechanism is not explained or is explained in vague words, there is no data from independent tests, and the seller avoids talking about returns. There is more in our note on the archived catalogue address (in Russian).
What should I do if a device did not deliver the promised result?
Keep the receipt, the product description and your own measurement notes. Under Russian consumer law, buyers are entitled to reliable product information, and stated properties must be backed up; other countries have their own consumer rules. Send the seller a written complaint.
Do objects that "improve a room's aura" help?
There is no verifiable data on any such effect. If a room feels uncomfortable, look at things you can measure: temperature, humidity, fresh air, noise and light. Each of them can be improved in clear, understandable ways.
Can I trust diplomas and awards on a seller's website?
A diploma on its own says little. Check who issued it, what for, whether it is listed in a public register and whether the document relates to this particular product. A trade-fair award is no substitute for proof of conformity.

Specific temperature, humidity and noise values are taken from the Russian standards GOST 30494-2011 and SanPiN 1.2.3685-21, and buyers' rights are described in general terms under the Russian Consumer Protection Law. Other countries use their own building, noise and consumer rules. The condition of your home's ventilation, heating and structure is assessed on site by specialists and your building manager or landlord, and health questions are a matter for a doctor.
