On the basic metrics alone, the score was 60.4 and the rank 3. The score is now 30.2 and rank 6 (▼ 3 places). The difference comes from buying motives: they measure what the buyer asks before deciding.
Biolan erottuu läpinäkyvällä hinnoittelulla: Trio-pienpuhdistamon ja harmaavesisuodattimien hinnat näkyvät julkisesti verkkokaupassa ilman kirjautumista, ja mitoitus talouden kokoon on kerrottu tarkasti. Valikoima on kuitenkin kapea eikä kata saostus- tai umpisäiliöitä, eikä takuuta tai sertifiointia mainita tuotesivulla.
Buying motives checked 15.10.2026 and basic metrics measured 26.8.2026 from public sources. The same formula for everyone, read the full methodology.
