Traditional air conditioning — a real problem

Tired of sweating and paying outrageous energy bills? 🥵

A traditional air conditioner costs over $1,500 to install, requires a technician, and sends your electricity bill through the roof. On top of that, you need to leave a window open for the hose — letting in heat and mosquitoes.

CoolMax® by Polara changes everything. No hose, no installation, no technician. Just plug it in and enjoy instant cool air at 74% less cost.

  • ❌ Traditional AC — CHF 1'500+, installation, high bills
  • ❌ Fan — moves hot air, no real cooling effect
  • ❌ Portable AC with hose — window open, heat and mosquitoes
  • ✅ CoolMax® — plug it in, enjoy it, save money
