Is it better to buy a universal remote control or replace my lost TV remote with the exact same remote control model?

Universal remote controls can manage most devices that work with remote controls. Universal remote controls also let you manage multiple devices with one controller. However, you must set up the universal remote to recognize your devices. Having the original controller for your TV is often preferable if a universal remote can't access special functions. A device-specific remote control recognizes the device right away but won't be able to control other devices.

What's the difference between carbon and HEPA filters?

Both types of filters improve air quality but in different ways. A carbon filter screens out odors, chemicals, and smoke. Carbon filters help make air smell fresh and odorless. A high-efficiency particulate air (HEPA) filter removes nearly all contaminants in the air passing through the filter, including mold, dust mites, pollen, and bacteria. HEPA filters help people with allergies breathe better and help reduce household mold and dust.
