Can Cascading DropDown HELP improve site architucture?

[BigBlaze205]

Our online stores is selling furnace filters.

http://www.furnacefilterscanada.com

We have 4 different qualities furnace filters and each of them are avaible in almost 50 different sizes.

My store is setup with almost 200 different products. ( 4 filtres X 50 sizes) None of them have variable.

I'm looking for a solution to help customers to find there furnace filter size fast and easy on our HOME page.

I find this cascading dropdown option

http://www.asp.net/ajaxLibrary/AjaxControlToolkitSampleSite/CascadingDropDown/CascadingDropDown.aspx

where I wiil setup 3 options to select:

filter width

filter lenght

filter depth

Will it be the best options?

Now my store is setup with categories and it is not the best solution.

This was a lots of work to create 200 different products. The reason I did this is because when searching in search engine, vistors will use such keywords:

16x20x4 filter

20x25x2 furnace filter

a/c filter 10x20x1

replacement filter online 20x20x1

16x25x5 filter toronto

and so on...

Must keywords request in search engine will included the furnace filter size.

Thank you for your help,

I think that Ajax drop down option would be a good improvement from a user experience perspective. But, being a Javascript/Ajax control, I don't think it will have an impact on your site architecture from a search perspective.

From Google's perspective the menus will not be populated with your product data because they will not trigger the ajax calls.
