Filtrete WHAF-1-CZ Whole House Air Freshener for HVAC Filter, Citrus Zest

I found that even with all the sent tabs pulled off for maximum smell, I couldn't smell anything after the first day. At first the smell is nice and subtle, but the next day I couldn't smell it at all. Also find it overpriced for one air freshener.Used in a townhome so not a large area.

This is a great idea. The scent is pretty subtle but there are ways to make it stronger, although I’m not sure why anyone would want to. Lasts about 2 months. I like that it isn’t overpowering like plug in air fresheners.

The product don’t work at all. During the first 10 minutes we have some smell in the home but after NONE at all

It just doesn't provide any scent within the house. Obviously those of us living here would become accustomed to it but we've asked visitors if they smell any scents and the answer is always 'no'. I was also away for a couple of days and when I returned, nothing.

Lavender is a nice smell, it's mild, unlike say Bacon or Citrus or gross incenses. This freshener is milder than my car air fresheners but about on par with my NON-essential oil Lavender candles (I miss gold canyon).Lots of complaints about people not being able to smell this scent however most lavenders these days are lavender+something stronger (vanilla, chamomile etc). I am very happy to find just Lavender. I can smell it each time the furnace runs although looking at how much scent is left after just a few days I'm not sure if it will last a month. There is an option to use as is, remove one strip or two strips to increase smell strength accordingly. I removed one strip because we just swapped furnaces due to a bad heat exchanger which left behind some exhaust smell in the ducts. I can no longer smell the exhaust smell.For my part I like the smell of just Lavender.... not chemical smells of something drowned in 'essential oils' etc, not the endless tiresome lavender + 'whatever' mixtures, I like just Lavender. I will order more.
