• 🧊 Gel absorbers (for example, Topperr 3104 or Zepter BioFresh) - work up to 6 months, often with flavorings.
• 🔋 Electronic ionizers (for example, Xiaomi Mi Air Purifier Mini) - kill bacteria and neutralize odors.
• 🧴 Freshener sprays (for example, Dr. Beckmann) — applied to the walls, valid for 1-2 weeks.
• 📦 Carbon filters —built into some models of refrigerators (Samsung RB30A3200SA, LG GB-B459SLQZ).

• Validity period (from 1 month to a year).
• Refrigerator volume (large chambers require powerful absorbers).
• Availability of flavors (not everyone likes “citrus fruits” or “sea freshness”).

Electronic devices are more efficient, but require connection to the network or replacement batteries. Gel absorbers are easier to use, but they need to be periodically “regenerated” (dried in the sun or in the oven).

⚠️ Attention: Some absorbers (especially those with a strong chemical composition) can damage the plastic of the refrigerator. Before use, check the compatibility with your model in the instructions.
