The quietest leaf blower currently available is the Echo Leaf Blower, which generates only 65 decibels. This blower is also free of the high-pitched whine that most leaf blowers produce.

I’ve been reviewing water filters for about 16 years. One of the best filters I’ve found is the Aquagear Water Filter Pitcher (made in the USA). This filter has been certified by ISO 17025 accredited labs tests to remove lead (97.5%), fluoride (90%), chlorine (99.99%), chromium 6 (99.87%), mercury (99.6%), trihalomethanes (99.99%), DDT (98.8%).
Pet dander is not the hair or fur of the animal, but is old skin scales which are constantly shed. Animal dander is extremely light weight and tiny in size (approximately 2.5 microns). It can stay airborne for hours.
Pets tend to shed a lot of dander, so you want a machine with a good pre-filter to stop pet hair reaching the main HEPA filter.
