Aquarium Air Pumps

The Tetra Whisper is possibly the quietest air pump on the market. The pump employes several features to reduce noise, including a dome shape that flattens sound waves, a suspended motor, rubber feet to diffuse sound, and internal sound baffling compartments. Available in five sizes: 10, 20, 40, 60, and 100, that accommodate tanks up to 100 gallons. The 10 through 40 gallon sizes have one outlet, while they 60 and 100 gallon models have two outlets. For tanks larger than 100 gallons, deep water, or multiple device applications, consider moving to the Whisper AP series.

Tetra replaced the former Tetratec Deep Water Air Pump product line, with the Whisper AP series. Their design makes them useful for deep tanks, applications with long air stones or setups with multiple airstones. Both models in the AP series are rated to pump air to 8 feed deep. The AP 150 is intended for tanks up to 150 gallons and has a single outlet, while the AP 300 is for tanks up to 300 gallons and has two outlets.

Hagen Marina offers a reliable product that is quiet and comes in four sizes: 50, 75, 100, and 200. The 50, 75 and 100 gallon models have a single outlet, while the 200 gallon model has two outlets. For a bit higher end model, look at the Hagen Fluval Q series.

The Hagen Fluval Q1 and Q2 air pumps are designed with a noise baffling chamber in addition to other features to make then quietest models the offer. The Q1 has two outlets and is intended for aquariums of up to 80 gallons in size, while the Q2 has one outlet and is designed for larger tanks of up to 160 gallons. Although they are quiet, they do not perform well for deep water or multiple stone applications. For those situations, consider a Luft air pump.
