See What Our Customers Are Saying

  • I have been out-of-touch with Air Delights for some years. When I decided to return, they were there, ready and able to help me. They even had my old order records from years back. This was a great help to me. I didn't even need to order new dispensers , because my old ones worked just like new.

  • Due to our order history they followed up with a phone call to ensure what was ordered was actually what we wanted. Turns out we ordered incorrectly. They made the adjustment on the phone and shipped the correct item.

  • From seeing the pop-up ad, through ordering the needed parts cheaper than factory pricing, to installing for a flushable toilet again---THREE DAYS ONLY!!! Impressive, outstanding, and better than most!

  • I've been using products from Air Delights for years and have loved all of the products that I purchased. There have never been any problems with the products or customer service. I've actually gotten some of my friends interested in the products.

  • I've dealt with you folks before so I know the kind of service I will receive. I like the fact that there is a place like yours that people can shop at and get the service we deserve. I've decided we needed another set of this product in our upstairs bathroom since we have someone else utilizing the downstairs bathroom. GREAT SERVICE!

  • They expedited shipping to me and got it her super fast and were MORE than courteous when I called. The Best!

  • This commercial supplier has always been patient with my household sized orders. They even called once when what I had ordered was not the same as my previous orders. Saved me from having to return a mistaken order. I love their air freshener products. It's not always easy to find air fresheners that I can use with my allergies.

  • Your company is the best.You save me money on the part that I needed.Also I will be order off your company if I need anything else.

  • Our Flushmate 503 developed a broken cartridge at 4PM central time. AirDelights is pacific time, so by the time I placed my order it was 2:47 pacific time. They sent the parts by FEDEX next day standard delivery. I had the parts in my hand in St Louis MO at 10:18 AM the next morning. The order was before 3PM so they shipped the same day.

  • Ease of ordering and length of time on delivery and the pleasing aroma of items purchased are all great! I will be purchasing more in the near future. Thanks to everyone involved with my order.
