Aprilaire 45 Replacement Water Panel for Aprilaire Whole House Humidifier Models 400, 400A and 400M

I WAS DELIGHTED WHEN IT ARRIVED. It was a bit delayed but was adequately boxed and I was able to replaced the old filter no problem. I had very good communication with the company via email. and the price was right. I will definitely consider ordering again.

Found these filters here at Atomic much cheaper than elsewhere. Shipping was slow but there was no hurry.

Arrived in a timely manor, packaged well and in good condition. Was also at the lowest price I could find. Very happy with the simple ordering process. Will need to check prices, but will most likely be ordering here again.

The filter I need is hard to find, so I was pleased that a google search revealed a company that had it in stock AND offered it at $15 cheaper than my previous supplier. On top of that, I received the filters in 3 days!

Received my order. It was in good shape. Thank you

After looking on Amazon, various local sources (found nothing), and a handful of sparse e-commerce dealers I found this vendor to have a specialized filter (wasn't disclosed when I purchased the HVAC unit!) at a reasonable price. I was very skeptical and also concerned that (1) the item price listed would change drastically with shipping costs or "other fees". False - I received free shipping and from order to my home 3 business days.
(2) that I was being scammed by either a non-OEM filter, or a fake business: FALSE!
(3) that the quality of the filter would somehow be compromised. FALSE!
Installed perfectly and our HVAC and air cleaner are happy again! I'll be a repeat customer!

Order and received just as promised and in good condition. What more could I ask. Thanks

Where is it? It's been 14 days since I ordered it. You claim it ships the next day. Something's wrong here.

Excellent item, delivered as expected and undamaged. Thank you

I have all good things to say about atomic filters. They deliver fast and free and are cheaper than everyone else. Thanks guys!

Perfect fit

I bought a 2 pack of these 18 months ago, same vendor, $30 less. Now same vendor via Amazon, $80 (I think) more than direct from Atomic. Even though all three instances were Atomic Filters. Lesson learned. Actually, lesson confirmed.

Filters as ordered, on time, good condition.

Filters work great. I will definitely order again.

The filter fit and worked as expected, came when expected and was a good price.

The shipping boc was of only one layer of carboard and the filter inside had several bends and creases after some work was usable. Either change shipper or use stronger box
