comfort without miracles: a guide to the home microclimate
Nanocomfort: home comfort without miracles
A cosy home is made of very down-to-earth things: temperature, humidity, a supply of fresh air, quiet at night and comfortable light. Each of them can be measured with a simple instrument or noticed through clear signs, and most of the time they can be improved without expensive equipment. This guide explains which conditions count as comfortable, where damp, stuffiness and draughts come from, and why claims that cannot be checked are best met calmly and with caution.
Comfort in a room does not need charging or tuning to the right wavelength. You measure it with a thermometer, a hygrometer and the quality of your own sleep, and you improve it with draught strips, fresh air and patience.
Where to start
Humidity
Signs of air that is too dry or too damp, droplets on the glass, dark patches in corners and the point at which mould becomes a job for a specialist.
Air
Airing, trickle vents, extract fans in the bathroom and kitchen: how a home can breathe without draughts or windows left wide open all day.
Quiet and light
Gaps, doors and soft surfaces against noise, daylight and evening light, and how to work out what exactly keeps you from resting and concentrating.

Check a room's microclimate in five steps
Set up a thermometer and a hygrometer
Place the instruments near the middle of the room, away from the radiator, the window and direct sun. Give them about half an hour to settle: the readings will then be closer to the air you actually breathe.
Write readings down morning and evening
For several days in a row, note the temperature and humidity at the same times. A single value tells you almost nothing, but a series of notes shows at which hours the room becomes stuffy, dry or chilly.
Inspect the windows and reveals
Check whether condensation collects on the glass and the sill, and whether there are dark spots in the corners of the frame and on the reveals. Constant moisture on a window suggests that the air is stagnant or the glass gets very cold.
Air the room and notice the smell
Walk into the room after being outdoors: stale, heavy air is obvious straight away. Open the window for a few minutes, then compare how it feels and what the hygrometer showed before and after.
Listen at night
Before going to sleep, switch off your devices and listen to what you can hear in the quiet: the street, the lift, humming pipes, neighbours' footsteps. Note the sources of noise, because they decide whether a draught strip, a heavy curtain or a talk with your building manager will help.
Common questions in brief
Do you sell instruments or microclimate devices?
No. Nanocomfort is an independent guide. We sell nothing, take no orders, run no tests and do not recommend shops. Our aim is to explain how comfort at home works and how to check the claims of manufacturers and sellers.
Do "nano plates", pyramids and similar items work?
There is no verifiable evidence that such objects change temperature, humidity, air quality or how you feel. When judging any claim of this kind, ask: what exactly is measured, who has checked it independently, what mechanism is said to cause the effect, and what you get back if there is no result.
What humidity at home counts as normal?
Under the Russian standard GOST 30494-2011, the optimal relative humidity for a living room is 30–45 % in the cold season and 30–60 % in the warm season. The optimal temperature is 20–22 °C in the cold season and 22–25 °C in the warm season. Other countries use their own building standards.
What should I do if mould appears in a corner?
First find and remove the cause: constant damp, a corner that gets very cold, a weak extract or a leak. A small patch is usually cleaned off and watched to see whether it comes back. If a large area is affected or the mould keeps returning, call in a specialist and tell your building manager or landlord.
About the project
This domain used to sell products that came with claims not backed by verifiable data. The current guide is not connected with the former website and does not sell or promote its products; the name simply stayed with the domain.
We write about the microclimate of an ordinary flat or house: how to keep the warmth in, keep humidity within sensible limits, let fresh air in, shut out noise and set up good lighting. We do not name brands or prices, do not invent studies, do not give medical advice and do not explain how to work on gas or electrical wiring yourself.

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.
