According to the Panasonic ES8243A Electric Shaver owner’s manual, the blade should be replaced once every two years and the foil should be replaced once a year. However, most people do not buy replacement blades at the same time that they purchase their new electric shaver. in fact, many people don’t even think about replacement blades after they’ve made the initial purchase of the shaver. Often times, they read the owner’s manual once, if at all, then throw it in the original box of the shaver and the box either ends up in the trash or in a closet somewhere never to be seen again. many people don’t even know that they need to change the blade and foil on their shaver until they start having performance problems. by that time, they’re absolutely clueless as to which replacement parts that they need to purchase.
This article is designed to take the guess work out of which type of replacement blade and foil are compatible with your Panasonic ES8243A. you can purchase replacement blades and foils in one of two ways, either separately or in a combo pack. It’s no surprise that the combo pack is the more cost efficient option. However, some may find that purchasing them separately is more convenient.
The compatible replacement foil is the Panasonic WES9161CL Shaver Replacement Foil. this foil is also compatible with the Panasonic ES8249K Arc IV Nano Vortex Wet/Dry Rechargeable Shaving System.
The compatible replacement blade is the Panasonic WES9068PC Inner Blade Replacement. this blade is also compatible with the Panasonic ES8249K Arc IV Nano Vortex Wet/Dry Rechargeable Shaving System, the Panasonic ES8103S Men’s 3-Blade (Arc 3) Wet/Dry Rechargeable Electric Shaver with Nanotech Blades, and the Panasonic ES8109S Men’s 3-Blade (Arc 3) Wet/Dry Nanotech Rechargeable Electric Shaver with Vortex Cleaning System.
Alternatively to buying the replacement foil and blade separately, you could purchase the Panasonic WES9020PC Combo Replacement Shaver Foil and Blade Set. this set comes with one replacement foil as depicted above and one replacement blade. Needless to say, the Panasonic WES9020PC Combo Replacement Shaver Foil and Blade Set is also compatible with the Panasonic ES8249K Arc IV Nano Vortex Wet/Dry Rechargeable Shaving System. the price in comparison to purchasing the blade and foil separately is about $5 so it’s really not a huge difference.
Because of the high cost of the replacement foils, most owners of this electric shaver prefer to buy the blade and foil one set at a time as opposed to stocking up. this makes sense considering that you don’t have to change them very often. However you choose to buy them, they are guaranteed to get your electric shaver in top running shape, and that’s all that matters.
