Food Grade Diatomaceous Earth 1 lb vs Harris Food Grade Diatomaceous Earth

Both are plain food-grade freshwater diatomaceous earth with no additives, so the choice comes down to size, packaging and track record. The 1 lb bag is OMRI listed, meets Food Chemicals Codex standards, and is packed with stainless steel machinery, but its resealable closure is the most common owner complaint. Harris gives you four times the powder in a tub, thousands of ratings behind it, and the same OMRI listing, which makes it the safer pick for household and pet use. Buy the 1 lb bag if you want a small, certified-clean supply for food or supplements; buy Harris if you want volume for pest control and a container that holds up.

• Choose the 1 lb food-grade DE if you want a small, OMRI-listed, Food Chemicals Codex batch for smoothies, coffee or supplement use and you don't mind transferring it to your own jar.
• Choose the Harris 4 lb if you need a large supply for pets, yards and crawling insects and want the brand with thousands of owner ratings behind it.
