      Scent-A-Filter attaches directly to your HVAC air filter, allowing your home’s air system to naturally distribute fragrance throughout every room. As air flows through your vents, it carries the scent evenly—eliminating the need for candles, sprays, or plug-ins.

      Nope! You'll only need the Starter Kit once. After that, your bi-weekly or monthly oil refills keep your home smelling fresh without replacing the air diffuser. If the pad seems to be worn, you can then purchase another.

      No! Our filters are designed to provide a subtle, consistent fragrance that enhances your space without being overwhelming. Unlike artificial sprays or plug-ins, Scent-A-Filter ensures a balanced, natural aroma throughout your entire home. You can reduce the amount of oil you put in the diffuser to reduce strength if necessary.

      Designed to last twice the life of a premium candle, depending on your system’s run time. For best results, replace it once the scent starts fade to maintain consistent freshness.

      Absolutely! Scent-A-Filter uses pure, non-toxic fragrances, free from harsh chemicals, synthetic aerosols, or artificial enhancers. It's a non-toxic, safe alternative to traditional air fresheners. You can see the full list of ingredients for all of our scents here: https://scentafilter.com/pages/ingredients

      Yes! Scent-A-Filter is universally compatible with all standard HVAC systems. Simply attach it to your existing air filter, and let your system do the rest.

      Scent-A-Filter not only adds a fresh, luxurious scent to your home but also helps neutralize odors from cooking, pets, and everyday life—keeping your space smelling fresh all month long.
