Looks nice and clean etc. Although you might want to vertically centre the "Filter Paper" and "Filter Bonding Adhesives" titles.
It looks professional but don't forget to put alt tag on your images. Not everyone use the same browsers...and help the disabled surf the site too.
But is there any use of alt tags these days from promotion point of view. I donnt thing google these days reads the alt tags at all...
Apart from using it to help ppl with other browsers and the blind .. maybe no. Unless it's pics with link. http://www.internet-search-engines-faq.com/alt-tag-linked-graphic.shtml
Looks ok to me, adjust some of the margins around some of the text and headings, some look a little outta place
