Here's how to find the model name for your air purifier:

Here are some typical places you can look when you don't know your model name or number:

Check the Unit Itself 

Some models (like many of the Honeywells) come with a model number plate (or a rating plate) where a model # can be found. This plate could be located on the underside, the interior, or elsewhere on the unit.

Some models (like most of the Austin Airs) come with a nameplate on the exterior of the unit. While you may not find the model number, you may find the model name (for example: Austin Air Pet Machine). This will help narrow it down for you.

Check the Packaging 

If you retained it, check the manufacturer's original box. Often, but not always, the model number and/or name will be printed on the manufacturer's box. It might also appear on a label affixed to the box.

If you have retained the shipping carton itself, some manufacturers (like Blueair) include the model name and/or number on the ship carton. It may also appear on a label affixed to the carton.

If you have the manufacturer's original box and/or ship carton, but the model name and/or number is not shown, check to see if any of the labeling includes a UPC number. This is typically 12 digits (and less typically 13 or 14 digits), and appears under the barcode. If so, go to: www.google.com and enter the UPC number (make sure to type in "UPC" with a space before typing in the number so Google knows it's looking for a UPC.

Check the Documentation 

If you have an original invoice or packing list, the model number could appear on this documentation.

If you have an Owner's Manual check the cover.Some manufacturers (Hunter is one of them) put the exact model name and number on the cover of the Owner's Manual. This is the key to finding your model in the filter wizard.

Sometimes manufacturers will put the air purifier series number(not the exact model number, but the series it comes from) on the cover of their Owner's Manual (more times than not, this is what Honeywell does). Typically, the first 3 or 4 digits of 5-digit number (at least in the case of Honeywell) can be used to narrow down your search.

In other cases (like on the Whirlpools), you may only see a number that looks on the surface to be more like a document number - it might even appear in an obscure area on the cover. However, this could help you get closer to the actual model number. For example, if the number in the lower lefthand corner of the cover page of your Whirlpool Owner's Manual reads "WP-AP510" then you own a Whirlpool Whispure 510 model. While you are still missing the rest of the digits that make up the full model number, this at least narrows the choices down.
