Many years ago, I took up an interesting practice- once a week, I purify and bless my home, usually on Saturday nights. Saturday night is an opportune time as many churches are celebrating a Vigil Mass around sunset.
A Saturday night purification serves two purposes- one is to cleanse the home of the past week's accumulation of (potentially negative) energy, and the second is prepare the home to experience the power of the Mass.
A third purpose might be to open up the home to be consecrated and dedicated- in my case, I dedicate my home to the Blessed Virgin Mary.
There are multiple ways in which the purification of one's home can be accomplished; through prayer, through a small ritual, through the use of Holy Water or incense (or both!), and so on.
Personally, I purify my home by summoning the Four Classical Elements of Earth, Air, Fire, and Water, and I add to this Spirit. I make the Sign of the Cross while speaking aloud word to banish negative energy and negative entities. Then I repeat the process with a blessing of the home and those virtues and such that I want in my home.
Other people may choose to simply recite the Our Father or the Hail Mary or some other set of prayers; perhaps someone lights a candle and recites the Holy Rosary.
Others may simply have so much spiritual energy in their home that they would find a Weekly Blessing to be redundant; that's valid, too.
Either way, a Weekly Purification is another way for us to live out our spiritual path.
