Say Goodbye to Smoke Odors! New Activated Carbon Filters for Heat Recovery Units

🔥 Why Does Air Quality Get Worse During the Heating Season?

During the colder months, outdoor air across Europe becomes noticeably more polluted. The main reasons are:

  • 🔥 Solid fuel combustion (wood, peat, coal)
  • 🚗 Vehicle heating and increased traffic congestion
  • 🌬️ Reduced natural air circulation due to weather conditions

These pollutants reach the air ducts and enter your ventilation system. While CleanFilter F7-class filters capture fine dust, resin, and soot particles, many harmful gases and volatile compounds still remain in the air.

☣️ Harmful Substances in Smoke

Even when burning wood, the air can contain aldehydes, ketones, phenols, and volatile organic compounds. When burning coal, painted wood, or furniture residues, the emissions become far more toxic and dangerous:

  • Toluene – ⚠️ affects the nervous system, causes dizziness and loss of coordination.
  • Benzene – ⚠️ highly carcinogenic; linked to leukemia and bone marrow damage.
  • Xylene – ⏳ irritates eyes and skin, affects the liver and kidneys.
  • Polycyclic Aromatic Hydrocarbons (PAH) – ⚙️ carcinogenic compounds that accumulate in soil and the human body.

These compounds are released even from small-scale heating and can easily enter your home through the ventilation system if not properly filtered.

🌬️ How Smoke Impact Decreases with Distance?

Studies show that even air several hundred metres from fuel combustion sites can still carry smoke-borne pollutants. The table below helps illustrate the levels of smoke impact by distance:

Distance from source Level of smoke impact Description
0–50 m ⚠️ Very high Strong smoke smell, soot, toxic compounds.
50–200 m ⏳ Medium Noticeable smell, elevated PM₂.₅, may irritate sensitive individuals.
200–500 m ⚙️ Low Weak smell, contamination nearly at background levels.
>500–1000 m ✅ Minimal Smoke has fully dispersed, negligible impact.

If you often detect smoke or odours entering your home through the ventilation system, consider installing activated carbon filters for your heat recovery unit to ensure cleaner supply air.
