This is a clone model of the GREENWAVE Dirty Electricity filters. Advantages of the GREENWAVE Noise Filter The biggest advantage is its powerful noise (including electromagnetic waves) removal effect. Any noise that cannot be removed using three of these noise filters cannot be removed by any other noise filter. We often receive feedback that the bass improves and the sound quality becomes clearer. Disadvantages of the GREENWAVE Noise Filter Due to its high absorption capacity, electromagnetic waves leak from the main unit's capacitor. The amount depends on the noise source, but measurements have shown values ​​similar to those of an IH cooking heater at maximum. For safety, please install it at least 50 cm away from humans. What will be sent: One completed clone of the GREENWAVE Dirty Electricity filter. From this time, we are aiming for further improvement in operation and stability by using high-performance capacitors with significantly improved quality. The capacitor upgrade version, which surpasses the original GREENWAVE, often had a greater noise attenuation than the original (compared to our company). The original has two-pin and three-pin (ground) versions, but the ground is not connected to the circuit, so there is no difference between them. The service outlet on the original unit is also connected in parallel with the circuit, so there is no difference in effect whether you plug the plug into the unit or into the adjacent outlet. The electricity bill for the noise filter itself is almost zero. We measured how many units are needed to get below 50mU (almost no noise) with an EMI meter. The noise level of a desktop computer was exceptionally high, exceeding 200mU, and it took three noise filters to finally get below 50mU. One for the refrigerator, one for the modem and wireless router, and one for the outlet with AC adapters, these were the places with the most noise in my house. Many people install noise filters near audio equipment, but it seems that suppressing the noise source is more effective. The effect was almost the same even if the installation location was an outlet in the next room, as long as it was within the same safety breaker.
