Yes this softener will be able to handle 28 grains of hardness. You will definitely be using more salt to handle the hardness but really what it boils down is grain capacity. The rule of thumb to calculate softener capacity needs is take the hardness in your water (28 grains / gallon) and then multiply it by the # of gallons used by each person / day. Average is 70 gallons per person. Times this value by 2 since it is a two person household which results in 140 gallons / day of water usage. We multiply 28 grains of hardness x 140 gallons = 3920 grains of hardness / day. Typical water softener regeneration should occur no more than ever 4 days but no more than 14 days / regeneration cycle. This means we can take a 44,000 grain softener divide that by 3920 grains / day = 11.22 days for your home to use up the water softeners maximum capacity. That being said, a high efficiency softer will rarely run itself to max capacity and will likely regenerate sooner which means your softener will on average likely regenerate every week which is an ideal interval. Go with the WHSE44 model from Lowes and it will suit your needs perfectly without regenerating too often and wasting a lot of water and salt.
