Air fresheners are products designed to mask or eliminate unpleasant odors in indoor spaces. They come in various forms, including sprays, gels, plug-ins, and scented candles. Many air fresheners contain fragrances that can create a more pleasant atmosphere in homes, offices, and vehicles. These products often use chemicals to neutralize odors or release pleasant scents into the air. Some air fresheners are made with natural ingredients, while others may contain synthetic compounds. It's important to choose air fresheners that suit your preferences and consider any potential sensitivities to fragrances or chemicals.
